Deanna Lacoste, Ph.D.


Associate Professor of Mechanical Engineering

Research Interests

Professor Lacoste‘s research interests are in plasma-assisted combustion and flame dynamics, with special emphasis on control of thermoacoustic instabilities by non-equilibrium plasma discharges. She is also interested in detonation and development of optical diagnostics for combustion and electrical discharges.
