Subrata Roy

Subrata Roy (Bengali: সুব্রত রায়) is an Indian-born American inventor, educator, and scientist known for his work in plasma-based flow control and plasma-based self-sterilizing technology. He is a professor of Mechanical and Aerospace Engineering at the University of Florida and the founding director of the Applied Physics Research Group at the University of Florida. Biography Subrata Roy earned his Ph.D. in engineering science from the University of Tennessee in Knoxville, TN in 1994. Roy was a senior research scientist at Computational Mechanics Corporation in Knoxville, Tennessee, and then professor of mechanical engineering at the Kettering University up to 2006. In 2006, Roy joined the University of Florida as a faculty member of the Department of Mechanical and Aerospace Engineering. He is a professor of Mechanical and Aerospace Engineering and the founding director of the Applied Physics Research Group at the University of Florida. He has also worked as a visiting professor at the University of Manchester and the Indian Institute of Technology Bombay. Scientific work Subrata Roy's research and scientific work encompasses Computational Fluid Dynamics (CFD), plasma physics, heat transfer, magnetohydrodynamics, electric propulsion, and micro/nanoscale flows. In 2003, Roy incorporated Knudsen's theory that handles surface collisions of molecules by diffusive and specular reflections into hydrodynamic models, which has been used in shale gas seepage studies. In 2006, Roy invented the Wingless Electromagnetic Air Vehicle (WEAV) which was included in Scientific American in 2008 as the world's first wingless, electromagnetically driven air vehicle design. Roy is known for introducing various novel designs and configurations of plasma actuators for applications in mitigation of flow drag related fuel consumption, noise reduction, and active film cooling of turbine blades and propulsion.
