I am an Assistant Professor in the Department of Thermal and Fluid Engineering at the University of Twente. My research focuses on heat transfer and fluid flow involving phase changes, with a particular emphasis on CO₂, investigated through both experiments and simulations. These phase changes include (de)sublimation, (pseudo)boiling/condensation, and melting/solidification under varying pressure and temperature conditions. Understanding these transitions is key to advancing energy-efficient technologies that use CO₂ as a natural working fluid - from cryogenic carbon capture and ultra-low-temperature refrigeration to high-temperature heat pumps, spray cooling, cold-chain logistics, and thermal management in electronic devices.

I hold a Ph.D. in Applied Physics from the University of Twente, where my doctoral research focused on the sublimation kinetics of CO₂. I hold a Master’s degree in Sustainable Energy Technology, with a specialization in Engineering Fluid Dynamics, and completed my thesis at Fraunhofer IWES (Germany). My academic journey began with a bachelor’s degree in Mechanical Engineering from the University of Pune, India. These experiences continue to shape my interdisciplinary approach to research in phase-change-driven energy systems.
