Biography:

Mehdi Raessi joined the Mechanical Engineering Department in 2010 following a postdoctoral study at NASA-Stanford University's Center for Turbulence Research (CTR). He obtained his PhD in Mechanical Engineering from the University of Toronto in 2008. During his graduate studies, he worked in the Centre for Advanced Coating Technologies (CACT).

Dr. Raessi's research is primarily focused on numerical simulations of interfacial flows and two-phase flows with phase change. Using numerical simulations, he has been studying the fluid flow and heat transfer in various applications including materials processing (spray coating), energy systems (fuel atomization), and environmentally friendly refrigeration systems. In addition to academic research and teaching, Dr. Raessi has industrial experience as a research and development (R&D) specialist and applied engineer.
