Dr. Paul Sapin received his MEng degree in 2010 in Mechanical/Thermal Engineering from ISAE-ENSMA, a Mechanical and Aeronautical Engineering School located in Poitiers, France.  He completed his Ph.D. in Fluid Mechanics and Heat Transfer at National Polytechnic Institute of Toulouse in 2014. The topic of his Ph.D. thesis was convective boiling heat transfer in porous media.

As a Post-Doctoral Research Associate in the Clean Energy Processes (CEP) Laboratory, his research focuses on the use of reciprocating-piston devices in energy-storage (e.g. compressed air, liquid air and pumped thermal electricity storage) and waste-heat recovery (e.g. organic Rankine cycle) technologies. Through the use of joint experimental and numerical approaches, his research aims (i) at understanding and predicting loss mechanisms in such engines and (ii) at developing design tools and innovations to mitigate these losses.
