Dr. Ghosh serves as Research Associate at the Advanced Propulsion Research Lab and as the Principal Investigator at the Aerospace Cardiovascular Research Lab . He holds a B.S. in Aerospace Engineering (2001) from the Indian Institute of Technology, and a MS and PhD in Aerospace Engineering (2008) from the University of Maryland, College Park. Dr. Ghosh’s Ph.D. thesis work focused on “Role of Density Gradient in Liquid Rocket Combustion Instability” which was sponsored by NASA.  He conducted a basic fundamental study investigating key physical mechanisms responsible for flame-acoustic interaction during the onset of acoustic mode combustion instabilities.  He performed both experimental and analytical studies varying key physical parameters that govern shear coaxial injector operations in thrust chamber assemblies and investigated the sensitivity of flame-acoustic interaction on those parameters.  Specifically, he found that flame-acoustic interaction was most sensitive to the propellant density ratio change.  This was for the most part an unexpected outcome to many researchers, who suspected either the velocity ratio or chemical composition to be the dominating parameter, until he came up with an elegant explanation showing baroclinic torque mechanism acting on the flame surface.  In 2008, Dr Ghosh was recognized with the Best Paper Award in Propellants and Combustion, given annually by the American Institute of Aeronautics and Astronautics (AIAA), which is the premier professional society in the aerospace engineering community for his paper entitles entitled “Effects of Fuel Density Velocity and Composition on Flame-Acoustic Interaction”. During his postdoctoral work, Dr. Ghosh  diversified into the investigation of cardiovascular flows pertinent to pathophysiologies and physiological conditions encountered in air and space flight. He and his coworkers are developing a microprocessor controlled, programmable, portable heart homologue that can be subjected to tilt tests, acceleration tests and for parametric tests of various concomitant pathophysiologies. With more than a decades worth of experience in flow measurement systems and instrumentation techniques, Dr. Ghosh is applying innovative diagnostic tools for characterizing fluid flows in the cardiac system. Simulation tools like COMSOL and SIMVASCULAR are being used to simulate flow in test geometries.  The group intends to offer critical engineering insights into the problems of VSDs with concomitant CV lesions,  orthostatic intolerance in astronauts and GLOC in air force pilots.
