Richard K. Chang Dr. Chang's research interest is in linear and nonlinear laser scattering from dielectric and metallic microparticles as well as from surfaces and bulk condensed matter. He is developing new optical diagnostic techniques that are applicable to combustion systems.

Alessandro Gomez Dr. Gomez's primary research focus is spray combustion. He is using various liquid dispersion techniques to study well-defined and well-controlled spray flames that are burnt under either laminar or turbulent conditions. Other research centers on the transport and burning of organic and inorganic "soot".

Marshall B. Long Dr. Long is pursuing the development of laser diagnostics for the analysis of reacting and nonreacting flows. He uses laser light scattering techniques for measuring temperature, species, and velocity in laminar as well as turbulent flows, with emphasis on the measurement of the three-dimensional character of turbulent flows and on the time evolution of structures in such systems.

Lisa D. Pfefferle Dr. Pfefferle's experimental and theoretical interest lies in fundamental reaction kinetics and species diagnostics in complex reacting flow systems. She has focused on the coupling between kinetics and transport in combustion systems in a range of combustion problems including catalytic combustion, pollutant formation, and combustion of chlorinated hydrocarbons. She has also developed new diagnostic techniques for hydrocarbon detection.

Daniel E. Rosner Dr. Rosner research centers on transport processes in chemically reacting flows, particularly in multi-phase combustion systems. His recent interests are in the microparticle nucleation; growth; dispersion, and deposition; the modelling of the deposit microstructure; and the transport (with emphasis on phoretic effects) of organic and inorganic particles in laminar and turbulent flames.

Mitchell D. Smooke Dr. Smooke's primary interests lie in the area of computational combustion. Current research involves computational studies of NOx and soot formation in flames, the modeling of multidimensional premixed and nonpremixed flames on shared memory parallel supercomputers, flamelet models for turbulent reacting flows, microgravity combustion; and modelling of solid propellant combustion.
