Subrata Roy (Scientist) is an India-born American inventor, educator, and scientist known for his work in plasma-based flow control and plasma-based self-sterilizing technology. As of 2020, 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.[1][2]

Biography

Subrata Roy earned his Ph.D. in engineering science from the University of Tennessee in Knoxville, TN in 1994.[3] 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.[4] 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.[1][2] He has also worked as a visiting professor at the University of Manchester.[5]

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.[1] In 2003, Roy incorporated Knudsen’s theory that handles surface collisions of molecules by diffusive and specular reflections into hydrodynamic models,[6][7][8] which has been used in shale gas seepage studies.[9][10][11][12] In 2006, a research team lead by Subrata 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.[13][14] Roy has also introduced various designs and configurations of plasma actuators for thrust generation, flow actuation, and propulsion with applications in mitigation of flow drag related fuel consumption, noise reduction, and active film cooling of turbine blades.[15][16] These designs and configurations include serpentine geometry plasma actuators,[17][18] fan geometry plasma actuators,[19] microactuators,[20][21] multibarrier plasma actuators,[22] and plasma actuated channels of atmospheric plasma actuators.[23]

Roy served as the Technical Discipline Chair for the 36th AIAA Thermophysics Conference in 2003, the 48th Aerospace Sciences Meeting (for Thermophysics) in 2010, the AIAA SciTech Plasma Dynamics and Lasers Conference in 2016, and served as the Forum Technical Chair for AIAA SciTech in 2018. Roy served (20052007) as an Associate Editor of the Journal of Fluids Engineering and served (20122017) as an Academic Editor of PLOS One.[2] As of April 2020, Roy is a nation appointed member to the NATO Science and Technology Organisation working group on plasma actuator technologies;[24] a member of the Editorial Board of Nature Scientific Reports; and, an Associate Editor of Journal of Fluid Flow, Heat and Mass Transfer.[2] Roy is a Distinguished Visiting Fellow of the Royal Academy of Engineering, a Fellow of the Royal Aeronautical Society, a lifetime member and Fellow of the American Society of Mechanical Engineers, and an Associated Fellow of the AIAA.[2]
