Associate Professor, Mechanical Engineering–Engineering Mechanics

Energy Thermo-Fluids (ETF) Area Director

  • PhD, Pennsylvania State University


Dr. Lee is an experimentalist interested in studying turbulent and spray combustion, including high-pressure diesel and gasoline spray and fundamental turbulent flames. Dr. Lee’s research interests are in the area of energy-thermal-fluid sciences, bio/alternative spray fuel combustion, surrogate fuel chemistry, advanced laser diagnostics, combustion dynamics of instabilities and stabilization, and non-equilibrium plasma-assisted combustion as alternative power conversion. Dr. Lee’s research emphasizes combustion experiment based on applications in energy, environment, and aerospace.
