Rupak earned his Bachelor's degree from the Manipal Institute of Technology, Udupi. He went on to complete his Master's degree from SASTRA University, Thanjavur in Thermal Engineering, and Ph.D. from IIT Roorkee in Mechanical and Industrial Engineering. During his academic career, Rupak focused on the experimental and numerical study of multiphase flows with phase change, contributing several papers to high-impact journals in the field.
After completing his Ph.D., Rupak joined the Bernal Institute at University of Limerick, as a postdoctoral researcher. There, he is presently working on “Factory in a box for personalised emulsions (FabPRO)” that involves the experimental and numerical investigation of liquid-liquid emulsions utilising hydrodynamic cavitation.
