About Me

Our group is involved in the field of energy and environmental engineering. The current area of research is gas hydrates formation & inhibition, methane recovery from natural gas hydrates, carbon dioxide capture and utilization. Study and characterization of gas hydrates at molecular level for innovative application like H2 storage and CO2 capture. We are also involved in process development & utilization of supercritical fluids, mainly focusing on the sacle-up potential of such processes.
