David Hung is currently an associate professor in the Department of Mechanical Engineering at Michigan State University. His research interest focuses on the spray atomization, flow sensing diagnostics, and sustainable energy systems, including areas such as internal combustion engines, alternative power systems, and renewable fuels for vehicle and aviation applications. He is currently working on a number of government-funded research programs which aim at fostering the use of ethanol-based fuels for vehicle transportation. Before joining MSU, he held employments in the automotive industry for over a decade where he was responsible for developing gasoline direct injection system and optical diagnostics for in-cylinder fuel mixture preparation and combustion measurements. David is active in the Society of Automotive Engineers (SAE) and Institute of Liquid Atomization and Spray Systems (ILASS). He is leading a task force in the SAE Gasoline Fuel Injection Standards Committee that includes an industry-wide team of automotive fuel system and spray measurement experts to develop and improve new and existing engineering standards for the global automotive research and development.
