Matthew Hall

Matthew Hall is a Professor in the Department of Mechanical Engineering at the University of Texas at Austin, holding the Louis T. Yule Fellowship in Engineering. He has been on the College of Engineering faculty since 1991, specializing in engine combustion processes, emissions reduction, and alternative fuels. His research includes engine controls, optical measurement techniques, spark ignition characterization, waste heat recovery, and lithium ion battery safety. He has published over 150 technical articles and serves as an Associate Editor for the Society of Automotive Engineers' International Journal of Engines.

Key research areas include improving diesel engine efficiency via the Rotating Liner Engine (RLE) technology (reducing fuel consumption by up to 35% at idle), optimizing thermoelectric generators for vehicle exhaust heat recovery, and exploring ammonia as a low-carbon fuel. He also investigates combustion-energized thermoelectric systems to extend drone flight range.

Notable awards include Fellow of the Society of Automotive Engineers. His teaching focuses on thermodynamics, including power cycle modeling and HVAC systems.

Recent publications emphasize cold start emissions, spark plug energy deposition, and ammonia-coal co-firing for emissions control. His work spans experimental studies, computational modeling, and interdisciplinary applications in energy sustainability.
