Pat worked for ExxonMobil Chemical Company for 37 years till his retirement in 2018. During that time, he held a variety of management and technical positions. Pat was Chief Scientist, Global R&D, and then Chief Polymer Scientific Advisor, from 2000-2018. Pat’s management, team leader, and technical efforts were largely focused on design, scale-up and commercialization of new polyolefins and their derivatives for a variety of applications including automotive, stretch films, uni- and biaxially oriented polyethylene films, separator membrane films for lithium-ion batteries (LIB), food packaging, elastomers, engine oil additives, and adhesives. A key enabler behind many of the application efforts was research driving commercialization of metallocene catalysis and supportation of such catalysts for operation in world scale reactors. From 2006-2010, based in part on his technical work on LIB membrane designs, Pat represented ExxonMobil Corporation through print and television advertisements, interviews, and a variety of invited talks and formal presentations focused on energy and transportation. Pat has authored or co-authored over 75 publications and is an inventor or co-inventor on over 150 US granted patents. He has given many invited technical talks and received a number of ExxonMobil awards, such as the Outstanding Scientist award, and in 2008 received the ICIS award for innovation. Over the years, he also led successful plant and customer product troubleshooting teams that have rapidly overcome major manufacturing issues. Since 2018, Pat has been an independent consultant and occasional expert witness. He is collaborating on research projects at the University of Houston and Baylor University. He recently formed a new company, Molecular Joinery, LLC focused primarily on novel, proprietary composite design and chemistry. He has a Ph.D. in chemistry from the University of Arizona, then held a post-doctoral position at Purdue University, and was awarded a National Research Council fellowship at the Naval Research Laboratory in Washington, D.C.
