Patrick L. Mills, D.Sc., P.E., Professor & Frank H. Dotterweich Chair
Dotterweich Chair, Frank H. Dotterweich College of Engineering
Patrick Mills recently joined the faculty at TAMUK in January 2006 as the Frank H. Dotterweich Chair and Professor in the Department of Chemical and Natural Gas Engineering. Before this appointment, he was a Senior Research Associate in the DuPont Company's Central Research and Development Department in Wilmington, Delaware where he was a member of the Chemical Science and Engineering Laboratory. During his 15+ years at DuPont, he used his research and development expertise in reaction kinetics, multiphase reaction engineering, transport phenomena, and experimental systems engineering to impact many technology areas in various DuPont businesses, such as Dacron, Nylon, Lycra, White Pigments, Fluoroproducts, and Nonwovens. In 1994, Dr. Mills developed the first successful research collaboration with the National Chemical Laboratory in Pune, India. These efforts served as a prototype that is now continuing through the former DuPont Invista group in the UK. He was also awarded an Engineering Excellence Award from DuPont in 1996 for development of the MARS system, which was an automated catalyst testing productivity device.
Before joining the DuPont Company, Dr. Mills worked for 10 years at the Monsanto Corporate Research Center at the World Headquarters in St. Louis and also at the GE Corporate R&D Center in Schenectady, New York. His research here utilized reaction engineering for the discovery and development of new molecules and processes in various businesses and technologies, such as agricultural and rubber chemicals, detergent hydrophobes, aromatic polycarbonates, functionalized olefinic polymers, and supercritical fluid chromatographic separations. He also served as a Research Associate Professor at Washington University in St. Louis from 1988 to 1990. In this capacity, he served as member of the business and technology team that commercialized the TAPï¿½(Temporal Analysis of Products) reactor system, which is an experimental system used by various university groups and companies worldwide for the study of heterogeneous catalyzed reactions. He also held appointments as Adjunct Professor of Chemical and Natural Gas Engineering at the University of Delaware and Washington University in St. Louis where he taught graduate courses in reaction engineering and applied mathematics. Dr. Mills is the author or co-author of over 110 publications in Chemical and Natural Gas Engineering and applied mathematics, has presented more than 125 papers at professional society meetings, and is named co-inventor on 2 patents.
