AWARDS
ASME Names Vande Geest Best
Young Researcher in Bioengineering
The American Society of Mechanical
Engineering recently honored the UA
College of Engineering’s Jonathan
Vande Geest with its Y.C. Fung Young
Investigator Award, which recognizes
signicant research in bioengineering.
Vande Geest received the award in
June at the 2013 ASME Bioengineering
Conference in Sunriver, Ore.
Vande Geest holds appointments in
biomedical engineering, aerospace
and mechanical engineering, the BIO5
Institute, and the applied mathematics
program. He credits a collaborative
multidisciplinary environment – which
draws together engineering, biology and
medicine – with his success in the eld.
“I have had the opportunity to work
with incredibly intelligent faculty and
students. More so than anything else,
that is why I have been successful,”
he said. “We tackle broad health-care
problems, look at the challenges from
many viewpoints, and devise solutions
that signicantly affect people’s lives.”
Vande Geest heads the College of
Engineering’s Soft Tissue Biomechanics
Laboratory, where researchers study
the structure-function relationship in
soft tissues and use that knowledge to
help develop new technologies for the
treatment of disease.
Among the projects in Vande Geest’s lab
are development of a tissue-engineered
vascular graft for coronary artery bypass
surgery, and a patient-specic device to
treat abdominal aortic aneurysms. “My
dad was a plumber, and my grandpa
was a plumber,” Vande Geest said. “I
think subconsciously I decided I was
Jonathan Vande Geest
going to study the aorta because it is the
largest pipe in our body.” Vande Geest
is also working on research projects
involving the diagnosis of unilateral
vocal fold paralysis and glaucoma.

Ricardo Sanfelice recently won an
award that puts him among the best in
the world when it comes to the highly
analytical and mathematical design of
control systems, which bring together
disparate aspects of a system and
make them work together.
Sanfelice, an assistant professor
in the aerospace and mechanical
engineering department, received
the Society for Industrial and
Applied Mathematics award for his
contributions to the design of hybrid
dynamical feedback controllers. His
research is centered on smart grids
and renewable energy, and unmanned
aircraft and vehicles.
The SIAM Activity Group on Control
and Systems Theory prize is awarded
internationally every two years to a
junior researcher. Sanfelice received
the award in July 2013 in San Diego
during the biennial SIAM Conference
on Control Theory. “I am very honored
to be recognized by my peers with this
award,” he said.
Hybrid feedback controllers, grounded
in mathematical theory and modeling,
help predict what hybrid systems – for
example, temperature control, car
cruise control, aircraft navigation,
communication systems, and ow
levels in water pumps – will do in
various circumstances, then determine
corrections for the inuences. “Without
feedback control many of the systems
we have these days would be extremely
difcult to operate,” said Sanfelice.
“Feedback control is everywhere.”
Sanfelice and his research team are
modeling ways to improve resiliency to
changes in energy sources, conversion,
load, and usage, thereby increasing
reliability of electric power supply.
Similarly, they are establishing ways to
detect and avoid threats of hacking in
unmanned aerial vehicles.
“I was always intrigued by automation
and excited about getting the systems
to do what I wanted them to do rather
than what they wanted to do,” said
Sanfelice, who coauthored the 2012
book, Hybrid Dynamical Systems:
Modeling, Stability and Robustness.
