Prof. Lacoste’s research focuses on plasma physics, flame dynamics and plasma-assisted combustion. Her primary interest is the use of non-equilibrium plasma discharges at atmospheric pressure to control thermo-acoustic instabilities. Lacoste aims to perfect the synthesis of plasma-generated electrical discharges and controlled explosions inside detonation engines for improved performance, and the expanded use of plasma actuators in modern combustion technology. Through the use of optical diagnostics, Lacoste discovered that non-thermal plasmas are extremely efficient for combustion enhancement within high-pressure environments, and could be instrumental toward making combustion technologies viable within a circular carbon economy. ​
