Introducing
Our New Dean
New Thinking
on Energy
Fa l l 2 0 1 1

In the last century, engineering has been transformed in
fundamental ways. As a discipline, it extended its intellectual
influence by enabling fields like biology, computing, architecture,
and others to build on traditional engineering research and design
methods; for example, we are now using nanoscience to design
drug delivery mechanisms. At the same time, engineering research
has acquired a fundamentally multidisciplinary nature. As a
practice, engineering has emerged as an integrative endeavor that
engages all other dimensions of our social and physical existence
by factoring environmental, business, esthetic, and personal
dimensions in the design and manufacturing process.
Within this broader context, the University of New Mexico School of
Engineering aspires to make a lasting social contribution through
its rich research portfolio and to have a deeply personal impact
on its students through progressive and creative educational
programs. We pursue research that is both fundamental and applied
in areas designed to greatly impact the way our society lives now
and in the future. We engage in teaching that both educates and
trains our students, giving them valuable skills that are in demand,
while encouraging them to follow their passion and expand their
horizons across areas of study, within and outside our school.
This issue is dedicated to sustainability as a research and education
theme and it is illustrative of our efforts to be faithful to the
vision outlined above. Research highlights focus on engineering
for energy efficiency in buildings, wastewater treatment, solar
cell technology, fuel cells, nuclear safety, and more. Student
involvement in research is amply visible throughout and so are
efforts to engage both industry and other disciplines in our
research endeavors.

“Buildings are the largest single consumer of energy —
they use 77% of the electric energy in the U.S.,” says
Andrea Mammoli, associate professor of mechanical
engineering and co-director of the Center for Emerging
Energy Technologies (CEET). Mammoli and an
international consortium are developing ways for
buildings to use energy more efficiently and more
wisely. Their vision is to seamlessly align production of
sustainable energy resources, including wind and solar,
with energy needs in residential and commercial buildings.
A Unique Opportunity
The consortium is Japan’s New Energy and Industrial
Technology Development Organization (NEDO), which
is working in partnership with UNM, Sandia National
Laboratories, Los Alamos National Laboratory, and
PNM, New Mexico’s largest electricity provider. With
21 American and Japanese companies involved, the
NEDO-led project is the only one of its kind in the U.S.
The group is using Mesa del Sol (MDS), a master-
planned community in Albuquerque, to research
the interface between buildings, distributed power
generation, and the power grid. It’s also using MDS to
test new smart grid technologies. MDS is a greenfield
development — undeveloped land without existing
technology networks — designed for healthy, simple,
sustainable living.

Building a Better Power Grid

Ph.D. student Birk Jones, Dr. Olga Lavrova, Dr. Andrea
Mammoli, and Jon Hawkins, Manager of Advanced
Technology and Strategy for PNM, stand in front of
the PV array that powers PNM’s Prosperity Project, a
system where utility-scale batteries help to manage
solar power to make it more grid-friendly.
NEDO is creating a “microgrid,” a
section of the power grid that can
produce and store its own power
through a mix of local renewable and
fossil energy sources. The microgrid
will be able to operate independently
of the main power grid. Alongside the
NEDO project, the DOE-sponsored
PNM Prosperity Energy Storage
project will test a battery the size
of eight shipping containers that
can store power generated by a
photovoltaic plant.
Mammoli will study how buildings
can absorb intermittent energy
produced by solar and wind power.
One strategy will be to use novel
energy storage solutions and digital
controls that manage power use
based on demand and the status of
local power generation.
The consortium plans to connect
MDS’s flagship building, the Aperture
Center, to the microgrid by the
end of the year. At the same time,
researchers will create a simulation of
the grid to test different scenarios in
real time without impacting buildings
or residents. Ultimately, the simulation
will be connected to actual buildings,
allowing researchers to test the
collective behavior of many smart
buildings and observe the operation of
real-life systems in detail. Research will
expand as MDS grows.
When the two-year research project
is complete, UNM will inherit the
NEDO hardware (valued at more
than $10 million), which will become
a substantial component of a unique
testbed that will put UNM at the
leading edge of smart grid research.
Multifaceted Research Effort
Mammoli has assembled a
multidisciplinary team to work on
the project. Olga Lavrova, assistant
professor of electrical and computer
engineering, is modeling multi–agent
behavior and analyzing the best way
to configure an automatic system that
includes many different nodes and
controls. She is also modeling battery
storage techniques to determine the
best use of PNM’s giant battery.
As the research progresses, other
faculty will get involved. Svetlana
Poroseva, assistant professor of
mechanical engineering, will use
an approach she developed to find
an optimal way for connecting
buildings and power sources with
one another so the microgrid will be
more resilient against multiple failures.
Melanie Moses, assistant professor
of computer science, will apply her
expertise in biological systems to
help design system architectures that
are more resilient. And Tom Caudell,
professor of electrical and computer
engineering, will use his expertise
in neural networks to develop ways
of effectively monitoring these
increasingly complex systems.
“The Smart Grid is a prototypical
example of a complex problem
that can only be solved with a
multidisciplinary approach,” explains
Mammoli. “At UNM, we have a team
of faculty and students from many
disciplines who interact to develop
innovative solutions.” d

A Model Teacher
A real-world education in energy efficiency
Engineering students and faculty learn
quite a bit from BERT. The exclusively
hands-on lessons include new ways to
control power usage in buildings, the
mechanics of thermal storage, smart grid
technology, and much more. This popular
teacher doesn’t take attendance, require
tests, or have a class schedule.
That’s because BERT is actually the
Building Energy Retrofit Testbed, a
living laboratory at the UNM Mechanical
Engineering building. SOE researchers
and students use BERT to see how
existing structures can become more
energy efficient — and stay that way —
by intelligently monitoring their own
operation and comparing it with an
accurate model running in parallel with
the real system.
When the ME building opened in
1980, it was a showcase of energy
conservation. Since then, new systems
and equipment have been added,
resulting in approximately $35,000 of
energy savings annually, according to
Hans Barsun, physical plant engineer.
Barsun is also pursuing a Ph.D.,
researching how to integrate BERT with
other energy systems on the electric grid.
Now, thanks to generous support
from Yearout Mechanical Inc., BERT’s
energy systems will be augmented by
new digital controls in all 70 air mixing
boxes that deliver heating and cooling
to the building’s rooms and by a series
of sensors that measure and monitor
airflow and quality throughout the
building. The added control and feedback
make it possible to effectively compare
building heating and cooling scenarios
against the energy simulation models.
Ph.D. student Birk Jones, who is
leading the implementation of the new
equipment, hopes that his research will
increase their abilities to accurately
predict energy use and reliably operate
energy systems within existing buildings.
BERT is also an excellent research
complement to the new NEDO
consortium studying microgrid
technology at Mesa del Sol (see previous
article). The experience gained through
BERT will help the team operate the
sophisticated microgrid equipment
installed by NEDO. For example, some
of the control strategies developed and
fine-tuned using BERT will be used in
the more demanding commercial
building environment.

“It’s a combination of
things. Resources are
being depleted pretty
quickly, especially because
emerging nations are
going to want to consume
energy at the rate we do.
There’s the climate to
consider. And water issues
because energy is very
intimately connected
with water. Everything is
tied together — so we
have to find a way to
use less energy.”

The nanoscale crystals and quantum
dots Ganesh Balakrishnan creates
are mere nanometers in diameter, but
they could help next generation solar
cells harness more power from the
sun by collecting light of different
colors or wavelengths.
Balakrishnan, assistant professor of
electrical and computer engineering,
leads a materials research group at the
Center for High Technology Materials
(CHTM). The team is combining
dissimilar materials to create high
efficiency, low cost solar cells. “We’re
trying something fundamentally new as
we work on next generation solar cell
technology,” says Balakrishnan.
Their goal is to integrate semiconductors
that absorb different wavelengths of
light into a single material by developing
new techniques to manipulate crystal
growth. Standard solar cell technology
made from silicon uses a single crystal
that catches only part of the spectrum.
“Solar energy is very broad spectrum
light, which means it has lots of different
wavelengths or colors,” explains
Balakrishnan. “If you can stack different
materials on top of each other, the first
layer could capture the first part of the
spectrum and the second layer could
capture the second.” The wafers of
novel materials Balakrishnan develops
could be used as solar cells in compact
but powerful solar arrays on rooftops or
other small spaces.
In one research project, Balakrishnan
is collaborating with scientists from
the National Renewable Energy
Laboratory to grow crystals of gallium
antimonide, a family of relatively
expensive compounds, on a substrate of
inexpensive gallium arsenide or silicon.
The substrate absorbs the visible and
ultraviolet part of the spectrum while
the gallium antimonide absorbs the
invisible infrared spectrum.
He’s applying the same idea but using
different structures in a second project
where he’s anchoring quantum dots
of a gallium antimonide on a substrate,
then surrounding the dots with
gallium arsenide.
“It’s getting enough people
to work on the problem
because it’s not going to
solve itself overnight. The
problem requires a
sustained effort and we’re
going to need the next
generation of researchers
to work on it.”

A traditional triple junction solar
cell design is one of the structures
that Balakrishnan’s lab is trying to
integrate with a variety of substrates.
In this case, the solar cell is being
bonded to a CVD diamond heat-
spreader to assess performance at
very high solar concentrations.

Decades of Expertise
Balakrishnan uses CHTM’s molecular beam epitaxy
(MBE) machines to create these novel materials. The
MBE allows researchers to build precise layers of
semiconductors by growing one atomic layer at a time.
“CHTM has one of the best MBE labs in the world for
quantum dots and antimonide semiconductors,” says
Balakrishnan. “Such dominance in these two research
fields can be traced to several decades of cutting-edge
epitaxial research by faculty members such as Steve
Brueck, Ralph Dawson, Luke Lester, Sanjay Krishna,
and Kevin Malloy.”
Balakrishnan’s novel materials find their way into a
collaborative network of faculty members working
in the area of photovoltaics. The team led by Luke
Lester, interim chair and professor of electrical and
computer engineering, fabricates the semiconductors
into working solar cells and also tests them in his
solar cell laboratory. Olga Lavrova, assistant professor
of electrical and computer engineering, works very
closely with the two teams to implement the solar
cells into systems.
In the future, these low cost, high efficiency solar
cells could be on rooftops near you, pulling more
power out of every ray of the sun and helping fuel
a clean energy future. d

Gaining The Competitive Edge
Special programs give undergraduates valuable training
In a secure lab at the Center for High Technology
Materials (CHTM), researchers move carefully around a
hulking, million-dollar molecular beam epitaxy machine
(MBE). One small mistake on the machine can result in
a repair bill that could easily run into the thousands —
or hundreds of thousands — of dollars. Which is why it
might be surprising to know that several of the
researchers are undergraduates.
Those students have special training with the MBE,
thanks to UNM’s Minority University Research Affiliate
(MURA) program. The prestigious Department of
Energy-funded program trains undergraduate students
for careers in the solar industry. The program is open
to all students but puts special focus on Native
American and Hispanic undergraduates.
MURA participants learn safety and lab procedures and
receive training on lab equipment, including the MBE. The
MURA also acts as a pipeline between SOE undergraduate
programs and the CHTM graduate program. “The goal
is to make UNM grads more competitive in the energy
area, whether they join our program or another program
elsewhere in the country,” says Ganesh Balakrishnan,
who runs the MURA with Olga Lavrova, both of whom
are assistant professors in the Electrical and Computer
Engineering Department.
Victor Patel (B.S., E.E.’11) is proof positive of the MURA’s
efficacy. Patel joined the program his senior year to
conduct optoelectronic and crystal growth research
with Balakrishnan’s group. “This program gave me great
hands-on research experience and helped me decide
what specialty I want to go in to,” says Patel. Now he’s
in graduate school at the University of Notre Dame and
credits his MURA experience with helping him stand out in
a competitive pool of graduate school applicants. “Notre
Dame was really impressed with my experience. They
acknowledged that most undergraduates don’t do this
type of research.”
The MURA is one of several special training programs at
CHTM. An NSF Research Experience for Undergraduates
(REU) trains undergraduates on nanosolar technologies,
and a Department of Defense Micro Autonomous Systems
and Technology (MAST) program gives students experience
in renewable energy technologies. In addition, Balakrishnan
helps manage an NSF scholarship program that awarded
annual $5,000 scholarships to five students studying high
technology materials last year.

Reel in a smallmouth bass from some
locations along the Mississippi River,
dissect it, and chances are good it will
be an “intersex” fish with both male
and female characteristics. According
to a recent U.S. Geological Survey
study, up to 70% of the smallmouth
bass at sites in the Mississippi,
Colorado, and Columbia River basins
are intersex; usually male fish with
egg cells in their testes.
These intersex fish are likely the result
of pollutants such as hormones and
pharmaceuticals that pass through
wastewater treatment systems and into
waterways at trace concentrations.
A subsequent U.S. Geological Survey
study showed that exposure to
estrogen puts these intersex fish at
greater risk of disease and premature
death. The presence of intersex fish
is a red flag for ecologists, as these
changes can signal widespread
ecosystem disruption.
Existing technologies for removal
of trace pollutants, such as reverse
osmosis, can be power-intensive
and expensive. As energy costs rise,
municipalities are looking for more
energy efficient technologies. Andrew
Schuler, associate professor of civil
engineering, may have the answer.
Schuler is focusing on using the
natural process of biodegradation
using integrated fixed film activated
sludge (IFAS) systems (pictured above),
which include thousands of faceted
plastic pieces that float in bioreactors
and create surfaces where pollutant-
removing bacterial biofilms can grow.
Because the plastic pieces simply
float in the water, they don’t use any
additional power at all.
Most IFAS pieces are made of
cheap, extrudable plastic. Schuler is
studying alternative materials with
different surface properties to attract
specialized populations of bacteria
that are better at removing hormones
and pharmaceuticals.
For example, researchers in Schuler’s
laboratory recently inserted sheets of
alternative materials into Albuquerque’s
wastewater treatment plant. After
four months of biofilm growth, his
lab extracted them and measured
their performance. “We found several
inexpensive materials that produced
biofilms providing much better estrogen
removal,” says Schuler. “The idea that
we can control bacterial populations
through manipulation of attachment
surfaces is really exciting.”
Now Schuler is studying how to adhere
specialized ammonia and hormone
removing bacteria to these surfaces.
By combining novel materials with
new 3-D shapes of attachment media,
Schuler aims to engineer biofilms
that remove a range of hormones and
pharmaceuticals. The result will provide
new technologies that use minimal
energy to protect our waterways.
The foundation for this research
garnered Schuler the prestigious 2008
Paul L. Busch Award, presented by the
Water Environment Research Foundation
to a researcher who is conducting
innovative environmental research, and
included a $100,000 cash prize. d
The New Possibilities of Plastic
Developing energy efficient materials that clean waterways
“One critical challenge is
addressing mobile energy
uses. We will be able to
meet many of our needs by
developing renewable
sources such as solar and
wind, but it’s doubtful we’ll
be able to run an airplane
on a battery. Efficiently
producing renewable liquid
fuels, such as algal biodiesel,
is going to be an important
piece of the puzzle.”

Fuel cell technology promises clean
power for electric cars, efficient
domestic combined heat-and-power
generation, and many useful gadgets,
but it has significant drawbacks. One
of the biggest is that current fuel
cell technology requires platinum
catalysts. Not only is platinum
extremely expensive, but consistent
access to it is uncertain because the
metal is heavily concentrated in
foreign-owned mines in South Africa.
That’s why researchers have worked for
years to develop fuel cell catalysts that
approximate the performance of
platinum without using any of the
precious metal. Earlier this year, a
consortium of researchers, including
Plamen Atanassov, professor of
chemical and nuclear engineering and
director of the Center for Emerging
Energy Technologies, made important
steps towards achieving that goal.
Atanassov is collaborating with
scientists from the Daihastu Motor
Corporation, a subsidiary of Toyota, to
create the world’s first platinum-free
fuel cell for an electric vehicle. Several
Japanese universities as well as private
and government organizations are
partnering in the effort as part of the
informal Creating Alkaline Fuel-cell
for Earth (CAFÉ) consortium.
This breakthrough fuel cell uses a
new type of polymer electrolyte
membrane that conducts electricity
by exchanging anions (hydroxyls), as
opposed to the proton-exchange
membranes that are popular today.
The membrane allows the use of
non-platinum catalysts for both
oxidation of fuel on the anode and
oxygen reduction on the cathode. The
catalyst is stable in an alkaline media
rather than a platinum catalyst, which
dominates in an acidic media.
Until now, alkaline membrane fuel cells
were inferior in their performance and
not as well developed as acidic models.
“This is an ambitious project. We are
replacing the paradigm with a new one,”
says Atanassov. “For the first time, an
alkaline membrane fuel cell has been
engineered for an electric vehicle.” If
this new technology takes off, it may
open the opportunity to introduce
automotive technology that is not
materials limited and constrained by
the scarcity of platinum. d

Jonathan Paiz was finishing his
first year as a doctoral student in
chemical engineering at UNM and
wasn’t sure which direction his
research should take. That’s when
Abhaya Datye, director of the Center
for Microengineered Materials (CMEM),
suggested Paiz pack his bags and
head to Eindhoven University of
Technology in the Netherlands, one
of the newest members of UNM’s NSF-
funded Partnerships for International
Research and Education (PIRE) grant.
Paiz was one of 15 students from the
U.S. who traveled to Europe as part of
the PIRE program. What the students
learned during their experience will
hopefully contribute to new frontiers in
the development of clean burning
liquid fuels and more efficient chemical
production from biomass.
Paiz says his ten-week experience
studying abroad was just the “kick
start” he needed. While in the
Netherlands, he worked with Dr. Peter
Thüne, a German professor visiting
Eindhoven University (www.tue.nl/en/)
who studies iron oxide catalysts. The
research was a departure from the
research Paiz had conducted at UNM.
“My experience in the Netherlands
gave me real motivation and new
ideas,” he says. “It inspired me to do
more research and to really get into
my subject.”
In the university’s advanced labs, Paiz
collaborated with students from other
European universities and found value
in that experience, too. “They’re
pioneers in catalysis. I learned that
their culture and work ethic is very
similar to ours,” he says.
Datye says cultural exchange is a key
benefit of the PIRE. “We see the value
of our students studying abroad
because they get a sense of what other
students at other universities are
learning and what type of research
they do,” he comments.
With support from the PIRE, Paiz
continued a long-distance collaboration
with Thüne during the school year. Paiz
returned to Eindhoven University, host
of the 2011 workshop for PIRE students,
this past summer to continue his
research and hopes to publish his first
paper based on the experience soon. d
Exploring New Horizons in Education and Research
Study abroad experience shapes students’ futures
“Our greatest challenge is
to capture and convert the
energy we get from the
sun into more useful
forms, such as liquid fuels
and electricity. We’re
addressing a global
problem and the solutions
are not going to come from
just one place. That’s why
we are partnering with
the leading institutions
around the world.”

When a nuclear criticality safety expert in France has a
question about the best way to recycle nuclear materials,
she can turn to colleagues in the U.S. for answers. And
when engineers in Russia need input on the safe processing
of uranium solutions, they have a worldwide network
of professionals to turn to for advice. These essential
connections are fostered by the Nuclear Criticality
Safety Group (NCSG), an organization that offers courses,
workshops, and networking to approximately 1,200
nuclear criticality safety professionals worldwide.
UNM has offered short courses and workshops on nuclear
criticality safety for decades, but the process was formalized
in 1991 when the NCSG was established. NCSG is directed
by Bob Busch, Ph.D., facility supervisor of the UNM Nuclear
Engineering Laboratory, and with administrative assistance
from Cheryl Brozena.
Busch also teaches a large portion of the
undergraduate curriculum of the Nuclear Engineering
program, including nuclear criticality safety courses.
UNM is one of only two universities in the nation to
offer such classes. “For the nuclear industry to remain
viable, we need engineers trained in the methods of safe
materials processing,” he explains. “Without these
courses, there would not be enough trained individuals
to oversee the safe handling of fissile materials.”
Nuclear criticality safety focuses on everything done to
fissile material outside nuclear reactors. Engineers in the
field research safe long-term nuclear waste storage, study
how to reprocess and recycle spent nuclear materials,
and develop ways to avoid accidents related to
handling nuclear materials.
A criticality event is distinctly different from the accidents
that happened at the Fukashima Nuclear Power Plant in
Japan because a criticality event is very localized and
involves nuclear material that isn’t within the reactor.
NCSG short courses and workshops are offered annually in
Albuquerque and every other year at an international
location. The NCSG organizes courses at three different
levels: practitioner, manager, and advanced. International
experts from various nuclear installations are invited to
teach the courses and interact with students. “People from
different companies generously donate their time to teach a
class,” says Busch. “That’s what makes our courses unique
from any other. The opportunity for students to interact with
mentors from around the world and other students is one
they won’t have anywhere else.” d

Participants write about the course:
“Exceptionally organized, excellent staff
insight, experience, and knowledge.”
“Valuable curriculum.” “Excellent for my job.”

As technology advances, researchers
are producing immense amounts of
data on everything from astronomy
to zoology. Ironically, much of that
raw data is just long, complex strings
of numbers or words that must
be analyzed and organized into
meaningful information. For that
job, researchers turn to computer
scientists like George Luger who has
a talent for creating tools that turn
data into possible answers that can
improve our world.
“Computation has become like Galileo’s
lens,” explains Luger, interim chair of
the Computer Science Department.
“Without that lens, Galileo would not
have seen the relationships between
the planets. Today, computer scientists
offer tools like that to help scientists
and researchers in many areas.”
Luger uses his interdisciplinary
background in computation, linguistics,
and psychology to understand and
augment human performance in a
range of industries from energy and
medicine to language and the weather.
Currently, Luger is using his expertise
to help a Seattle-based company
improve the efficacy of the controls
it develops for optimizing energy use
in large buildings. Using artificial
intelligence techniques such as
rule-based systems and case-based
reasoning, Luger creates control
systems that can think like a human
in real time. The controls are housed
in decision-making modules that
plug in to the various switches on
the building’s heating and cooling
components. “It’s about understanding
a complex situation and being able to
put together rules that can save
energy,” explains Luger. “The AI
system can make suggestions and
implement them. Then it can take
feedback from the implemented
rules to make adjustments.”
Outside of the energy field, Luger has
joined with Vince Clark, associate
professor of translational neuroscience
at the MIND Research Network, and
Sandia National Laboratories to
employ probabilistic modeling for
creating computer models of how
problem-solving information is stored
and retrieved by human subjects.
Clark, Luger, and other colleagues
studied the functionality of
components of the cortex and
created computer models of how
problem-solving information is
stored and retrieved by subjects.
They sampled data points from fMRI
images to induce a model that would
explain the subjects’ behaviors.
They discovered that one group of
subjects answered questions using the
memory component of the cortex; the
other group used the prefrontal cortex.
This data reflected the two types of
answers the subjects produced when
solving the problems. “It was really
interesting that people were using
different parts of their cortex,” says
Luger. Findings may be applied to
future studies on cortex functionality. d
Harnessing the Power of Data
Luger’s research converts data into answers
“It’s about understanding a complex
situation and being able to put together
rules that can save energy.”

Luger’s book, Artificial Intelligence: Structures and
Strategies for Complex Problem Solving, is printed in
five languages and is now in its sixth edition.

Born in Bucharest, Catalin Roman
decided to pursue computer science
and an academic career at the age
of 14. He was able to fulfill his dream
when he became the recipient of a
Fulbright Scholarship.“It was literally a
one in a million chance, and I got the
opportunity,” says Roman.
After earning his doctorate in
computer science and engineering
from the University of Pennsylvania,
he joined the faculty of Washington
University in St. Louis. As the head
of the Department of Computer
Science and Engineering, Roman had
a significant impact on its research
expansion, faculty growth, and
standing in the University and the
country. As a researcher, Roman and
his collaborators have made seminal
contributions to the emerging area of
mobile computing.
1. In your career, what are
you most proud of?
I’ve always felt that shaping students’
lives and helping my colleagues do the
same has been the most important
thing that I’ve done as a faculty and as
an administrator.
2. What is one of the UNM School of
Engineering’s greatest strengths?
People are the SOE’s greatest strength.
We have a very diverse, intelligent,
creative group of people here.
3. What is one of the
SOE’s challenges?
Most of the challenges will come from
the gap between resources and our
high aspirations. For a public institution
in this economic climate, private and
corporate support is crucial. In addition,
we need to maximize how we use
our intellectual and organizational
resources and our creative energy.
4. What is the SOE’s
greatest potential?
It’s simple — impact. The school has
incredible potential and we have to
leverage it to help students embark
on exciting careers, contribute to
economic development, and solve
global challenges.
5. What are some changes you’d
like to make at the School?
I hope to increase the visibility of
the school locally, nationally, and
internationally. I plan to have the
school more deeply involved with
governmental, public, and private
institutions across New Mexico and
have it emerge as a major contributor
to economic and social developments.
Our faculty is already involved in many
initiatives that cut across school and
departmental boundaries in areas
such as materials, renewable energy,
biomedical engineering, and high
performance computing. My vision is
to make collaborative education and
research the norm in our university.

Alumni, Supporters, and Friends
Endowed Fund Honors Longest-Serving Dean
School of Engineering alum John Farris (1954 BS ME) is the son of Marshall E. Farris, the SOE’s
longest-serving dean (1931-1960), and has fond memories of when his dad was dean. He also
remembers his father’s frustration when opportunities arose for the School and hearing the words,
“There’s just no money for this.” Farris recalls the time his father had to turn down a gift from the
Army Air Corps — a P-38 fighter aircraft — because he didn’t have the funds to create a secure
place to display it.
Farris and his wife Jo Margaret have created an endowed fund that can be used by the dean for just
such opportunities. The fund will be at the dean’s discretion to use to support students, faculty, and staff
for scholarships, travel, special projects, and other activities. “This fund is something my dad would have
loved to have had to maximize opportunities for the School,” says Farris. “It’s dedicated in his honor.”
Gifts Invest in Faculty and Students
“Strong academic credentials, demonstrated experience and
dedication to mentoring with distinguished records in both teaching
and interdisciplinary research,” describes some of the criteria for a
newly-established endowed professorship in biomedical engineering.
The description also fits David Whitten,
research professor in the Department of
Chemical and Nuclear Engineering and the
Interim Director of the Center for
Biomedical Engineering (CBME). An
internationally known researcher and
author, Whitten has been a thesis advisor
and mentor to more than 38 Ph.D. students
and has co-authored scientific papers with
more than 275 colleagues. Since 1997, he
has served as Editor-in-Chief of Langmuir, a
peer-reviewed interdisciplinary journal
published by the American Chemical Society.
Whitten and his wife Jo, coordinating editor of Langmuir, recently made a
legacy gift commitment to fund an endowed biomedical engineering
professorship as well a current gift in the form of a fellowship to support
students who are pursuing a graduate degree in biomedical engineering.
“David and Jo Whitten’s generous gifts will help the School of Engineering
attract and retain the brightest, most diverse students as well as add faculty to
our biomedical engineering program,” says Dean Catalin Roman. “The Whittens’
decision to support UNM is a true compliment to the School of Engineering.”

Former Student Thanks Professor For Changing His World
In 1962, when Frank Evans was in graduate school in Electrical
Engineering, he was excited by the idea of space exploration
and wanted to take courses outside of his major to make his
education more attractive to potential employers. Professor of
Mechanical Engineering Fred Ju taught those courses. “Frank’s
final paper on Orbital Mechanics was so good, that I kept it until
I retired from UNM,” says Professor Ju.
During a long career with TRW Systems, Evans worked on many
space exploration projects. “Professor Ju’s courses helped
me get a great job in the Apollo program,” says Evans. “I am
profoundly grateful to Professor Ju and the University for
providing me with this opportunity.”
Evans and his wife Janet, a retired member of the Marquette
University Political Science faculty, recently created the Fred Ju
Fund to recognize Professor Ju’s role and provide need-based
scholarships to potential engineering students.
Matching Corporate Interest With SOE Needs:
Yearout Mechanical Supports Retrofit Research
Yearout Mechanical Inc. is working with UNM’s Mechanical
Engineering Department on a special project involving intelligent
building energy systems controls. The project, Building Energy
Retrofit Testbed (BERT), will use the 31 year old Mechanical
Engineering building on UNM’s main campus to test new ways to
retrofit old buildings to be energy efficient (see page 5).
“We believe that the information
and advances that will come
out of the BERT program will be
a foundation to build on in the
future, not only for our company
but for the industry as a whole,” says
Kevin Yearout, CEO of Yearout Mechanical, Inc.
Honoring the Work of a Loved One
Marvin Duphorne, a longtime resident of Albuquerque, died
on December 6, 2010. A UNM Mechanical Engineering alum,
Duphorne worked for global companies such as Boeing, Pantex,
Singer, Intel, and Allied Signal, and concluded his career at
Honeywell on Kirtland Air Force Base.
His wife Patsy, a UNM College of
Nursing alum and an assistant
professor of nursing, and her only
son, Dante, a UNM Architecture and
Planning alum, wanted to honor him
by creating an endowed scholarship.
The scholarship will be targeted to
non-traditional engineering
students. A unique twist to this gift
is that Dante’s employer, Electronic
Arts Inc, a major American
developer and distributor of video
games, has a matching gift program that allows him to
maximize his donations. Patsy says, “We created this scholarship
as a living legacy to honor Marv’s contributions as a mechanical
engineer and to assist undergraduate students in pursuing
their goals in engineering.”
