Stephen R. Turns is Professor Emeritus of mechanical engineering at The Pennsylvania State University. His research interests include combustion-generated air pollution, other combustion-related topics, and engineering education pedagogy. Turns was the recipient of the 2009 ASEE Mechanical Engineering Division Ralph Coats Roe Award and has been the recipient of several teaching awards at Penn State. He is the author of An Introduction to Combustion: Concepts and Applications (3rd edition, 2011), also appearing in Chinese, Korean, and Portuguese, and of Thermal-Fluid Sciences: An Integrated Approach (2008). Turns is a fellow of the American Society of Mechanical Engineering (ASME). Laura L. Pauley is Professor of mechanical engineering at the Pennsylvania State University. She teaches courses in the thermal sciences and conducts research in engineering education and computational fluid dynamics. Pauley has worked on grants focusing on aspects of engineering education including classroom experiments, presentation skills, and the climate for women in engineering. She has also initiated efforts in curriculum reform and experimental case studies for required courses in mechanical engineering. She is the recipient of Undergraduate Program Leadership Award (2003) and was selected as the first Arthur L. Glenn Professor of Engineering Education. Pauley is a fellow of the American Society of Mechanical Engineering (ASME).
