​Professor Cha‘s research interests are in combustion and plasma science and technology, which includes flame dynamics, syngas combustion, hazardous gas treatment, syngas generation, and developing novel plasma sources. More recently, he has focused his interests on plasma assisted combustion, including plasma fuel reforming, electrical control of flames, plasmas in liquids, and interaction between electrical discharges and flames. These research areas can be applied to internal combustion engines and gas turbine engines to solve related emission, combustion stability, and fuel flexibility issues.
