Vamshi Avadhanula Projects

Projects with ACEP:

1. Waste heat recovery for Heating from Diesel Engines.

2. Testing of 50kW "GreenMachine" Organic Rankine Cycle.


Vamshi is a Ph.D. candidate in the Mechanical Engineering Department under the guidance of Dr. Chuen-Sen Lin. As part of his Ph.D. project he worked with ACEP on testing the 50kW Organic Rankine Cycle “GreenMachine” for its reliability and performance analysis. Presently Vamshi is working on GreenMachine field testing in Tok, Alaska. Vamshi’s area of interest includes waste heat recovery methods from diesel engine generator sets, thermodynamic cycles, and heat-to-power conversion systems.

Marc Mueller-Stoffels' CV

Marc Mueller-Stoffels is the lead researcher for the Power Systems Integration (PSI) Program at the Alaska Center for Energy and Power (ACEP). Marc's research focuses on the integration of variable generation sources into isolated micro grids. Most recently he has lead the testing of an inverter-battery system to enable diesel-off mode in high contribution wind scenarios. Prior to joining ACEP, Marc has developed regional scale climate models with focus on Arctic sea ice, and has chaired a small software company specializing in optimization algorithms. Marc holds graduate degrees in physics from the University of Alaska Fairbanks and Otago University, New Zealand.

George Roe Projects

Projects with ACEP:

  • Scenarios Planning and Tracking of Global Energy Markets

George Roe is a research professor with ACEP and the Institute of Northern Engineering at the University of Alaska Fairbanks. His focus areas include energy and energy management, with emphasis on their relation to sustainable community development and capacity building. George has 35 years of experience at Boeing, where he worked in research and development efforts for a range of technologies (e.g., thermal management, vehicle subsystems, crew protection, energy harvesting, energy storage, alternative energy) and their integration with products sold by Boeing and its team mates. He has served in both engineering and management capacities on multiple company, industry and government-funded endeavors. His responsibilities have addressed technology maturation in the areas of energy management systems for aircraft. He holds Bachelor and Master of Science degrees in Mechanical Engineering from the University of Washington.
