Associate Professor

Dr. Genzale began at Georgia Tech in December 2010.  Prior to arriving at Georgia Tech, she was a post-doctoral researcher at Sandia National Laboratories’ Combustion Research Facility in Livermore, California.  There, she applied laser-based measurements in combusting fuel sprays to study the mechanisms of pollutant formation and combustion inefficiencies that occur in direct-injection diesel and gasoline engines.  During her graduate work at the University of Wisconsin – Madison, she worked on the development of computer models and optimization tools to explore new high-efficiency low-pollution engine designs.

In 1992, he joined Georgia Institute of Technology as an associate professor and became a professor in 1997. He is currently the Hightower Professor of Engineering in Georgia Tech. Professor Menon is a world renowned expert in large-eddy simulation of turbulent reacting and non-reacting flows and has developed unique simulation capabilities to study pollutant formation, ozone depletion in high-altitude aircraft jet plumes and combustion in gas turbine and ramjet engines. He has been (and is currently) a principal investigator for a wide range of research projects funded by NASA, Department of Energy, Air Force Office of Scientific Research, Office of Naval Research, Defense Threat Reduction Agency. His work has been (and is also) supported by many industries including General Electric, Pratt & Whitney, Solar Turbines, Boeing, Safran (France), Hyundai (S. Korea), JAXA (Japan), IHI (Japan) and Rocketdyne-Aerojet. He has published and/or presented over 395 papers. Professor Menon is a Fellow of AAAS, Associate Fellow of AIAA, and a member of the American Physical Society, the American Society of Mechanical Engineers, the Combustion Institute and the Sigma Xi.

Associate Professor

Dr. Devesh Ranjan is the founder of Shock Tube and Advanced Mixing Lab. He started as Assistant Professor in the department of Mechanical Engineering at Texas A&M University in 2009. Since 2014 he has been an Associate Professor in the department of Mechanical Engineering at Georgia Tech.


Dr. Seitzman joined Georgia Tech in 1994. He has expertise in the fields of optical flow diagnostics and sensors, combustion and combustion control, high temperature gas dynamics, laser spectroscopy, flow-field imaging and solid propellant combustion. He has authored more than 150 papers on these subjects. His experience includes development of optical sensors and diagnostics based on planar laser-induced fluorescence, line-of-sight absorption, chemiluminescence, particle image velocimetry, Raman scattering and laser-induced incandescence of soot, and their application in systems ranging from laboratory flames to high pressure combustors. Dr. Seitzman helped pioneer the development of planar laser-induced fluorescence (PLIF) and laser-induced incandescence as quantitative measurement techniques, and optical sensing of flame emission for active combustion control. The applications for this work include aircraft and spacecraft propulsion, ground-based power production, and heating systems.
