Research

My research focus is on renewable energy technology and implementation (resources, hybrid designs, policies, and society) as well thermal fluid system design optimization for improved energy system performance. My recent thrusts have been:

  • Developing online courses for University wide Professional Masters in Renewable Energy and Sustainability Systems.
  • Solar thermal system bubble pump modeling and design optimization.
  • Wind energy system design optimization under site specific conditions
  • Extreme offshore wind analysis and translation to U.S. offshore design standards
  • Modeling the impact of various levels of smart grid implementation on the utility grid
  • Heat pipe design for thermal energy harvesting

Recently Funded Research/Programs:

  • Pennsylvania Wind for Schools Program.” Three-year program funded by NREL, December 2010.  PI.
  • “Proper Siting of Building Integrated Wind Turbines,” One-year study internally funded through a competitive process at ARL, November 2009.  PI.
  • "Wind Energy in the Built Environment: Connecting Aesthetics and Performance," April 2010. Two year study funded by PSIEE Sustainability Seed Grant Program. Co-PI.
  • "GridSTAR: Grid Smart Training Application Resource Center," Three-year study funded by DOE, Oct. 2010. Key Participant.
  •  “Wind Energy Workforce Development: Engineering, Science, & Technology Meeting the Needs of the Future, Now,” Two year program funded by the Department of Energy, December 2009.  Key Participant.
  •  “Utility Grid Automation and Risk Management,”  One year study funded by: Lockheed Martin, December 2008. Co-PI.
Education & Background: I received my MS and PhD in Mechanical Engineering at Georgia Tech in 2001 and 2003, respectively, and my BSME at Penn State in 1999. My graduate research was focused on energy system design optimization. Upon finishing my PhD I joined my former advisor, Sam Shelton, in starting up the Georgia Tech Strategic Energy Institute. In this position I performed a variety of alternative energy technology assessments, investigated the feasibility of offshore wind development in the South Atlantic Bight, and worked with a multidisciplinary group to determine effectiveness of converting southern pine to ethanol. In March 2007 I moved back to Pennsylvania and joined the Applied Research Laboratory to assist with their efforts to apply their extensive energy system development expertise to the renewable energy industry. Currently, I am coordinating renewable energy workforce development efforts for the departments of Aerospace Engineering and Architectural Engineering. I also am the Director of the DOE Sponsored Pennsylvania Wind for Schools Program.
Teaching:

EGEE 438: Wind & Hydropower Energy Conversion. This course examines the principles of sustainability and renewable energy conversion with emphasis on wind and hydrokinetic energy resources. Offered each Spring.

EGEE 597 D: Distributed Energy Engineering and Management. This survey course examines the theories and practices of distributed energy production and management in the context of regional and integrated energy grid structures. Offered Spring 2010.

A E 897 A: Solar Project Development. This course examines the theories and practices of photovoltaic system business development and financing. The course builds upon a fundamental understanding of systems engineering, engineering economics and building energy systems to prepare students to conduct investment grade solar energy system proposals and financing plans.
