Brian Polagye is an associate professor in the Department of Mechanical Engineering and the Director of the Pacific Marine Energy Center, a collaboration between the University of Washington, Oregon State University, and the University of Alaska Fairbanks. His research focuses on marine renewable energy conversion and its environmental effects, with the ultimate goal of developing cost-effective, sustainable approaches. He is also the convener for the development of an international standard to characterize the sounds produced by marine energy conversion systems (IEC TC 114 PT 62600-40).

Brian Polagye's lab research group focuses on the conversion of marine renewable energy resources (river, tidal, and ocean currents, as well as waves) to mechanical power. One thrust area is optimizing the hydrodynamics and control of conversion systems, primarily through laboratory experiments and field demonstrations. A second thrust area is developing and applying instrumentation necessary to characterize energetic sites, with emphasis on marine energy resources, underwater sound, and integrated instrumentation packages.
Current research topics include:
- Studying the hydrodynamics of cross-flow current turbines to increase individual turbine and array power yields
- Studying the hydrodynamics and control of multi-body wave energy converters
- Studying the effects of channel blockage on turbine performance
- Developing low-cost drifting instrumentation packages for volumetric swarm sensing
- Developing integrated instrumentation systems for marine energy projects
- Measuring the acoustic characteristics of wave energy converters
