Faculty Members   

Dr. Shapour Azarm 
Professor of Mechanical Engineering

Dr. Amr Baz 
Professor of Mechanical Engineering, Director of Small Smart Systems Center

Dr. Greg Jackson 
Assistant Professor of Mechanical Engineering
Dr. Jackson has established growing research programs in lean premixed flame stability and in catalytic reactor flows for clean combustion, exhaust aftertreatment, and fuel reforming.  His research includes the study of catalytic reactors for minimizing flame instabilities and NOx emissions in combustion systems and for producing hydrogen from hydrocarbons for fuel cell operation. Other efforts are underway to study novel techniques for improving lean flame stability in low emissions combustion systems and to address heat and mass transport in novel fuel cell designs. Before joining CEEE, Dr. Jackson spent several years at Precision Combustion Inc. where he managed several product development and research projects related to ultra-low emissions and ignition of gas turbine combustors.

Dr. Michael Ohadi
Professor of Mechanical Engineering 
Dr. Ohadi is group leader for heat/mass transfer applications at CEEE. He has more than 15 years of industrial and academic experience in areas of heat transfer, fluid flow, and thermal energy conversion.  Since 1985 his research has focused on active and hybrid augmentation of single-phase and phase-change heat transfer with particular emphasis on the use of electrical fields.
