Research Interests
System design and control of environmentally sensitive energy
technologies and the implementation of such technologies into the built
environment.
Past Energy Experience
National Fuel Cell Research Center (2002-present)
I have been involved in fuel cell research at the national fuel cell
research center since 2002. My focus has been in system design,
dynamic modeling, control and grid connectivity of integrated fuel cell
systems.
Dynamic Modeling:
Dynamic models of PEMFC and SOFC systems have been developed for system
design and control analysis. Developed dynamic models have been used to garner insight into SOFC
transient behavior and to develop, test, and demonstrate integrated fuel
cell systems and controls.

Integrated System Controls:
Controls to improve the transient performance of fuel cell systems have
been developed. By understanding fuel cell transient characteristics
integrated system designs and control concepts are being developed to
substantially improve the transient performance of future fuel cell systems.

System Design Analysis:
System design analysis is being conducted to understand system
operating limitations, system trade-offs, and to improve system efficiency
and transient performance of solid oxide fuel cell operation. Analysis
is being conducted for fuel cell systems in applications ranging from
aerospace to large coal power plants.

GE Energy (Summer 2007)
In the summer of 2007, I got the opportunity to intern at GE Energy
in Greenville, South Carolina. My project was to evaluate fuel
pre-processing for lean premix combustion.

Boeing Commercial (Summer 2002)
In the summer of 2004, I got the opportunity to intern at Boeing
Commercial in Seattle, Washington. I analyzed the use of solid oxide
fuel cell gas turbine hybrid systems in aerospace applications in
collaboration with Boeing, NASA and the National Fuel Cell Research Center.
