Dr. Paul M. Mathias is a chemical technologist with over 38 years of broad experience, and a specialization in physical properties and process modeling. He currently works as a Technology Director and Senior Fellow at Fluor Corporation where he focuses on process modeling and technologies such as CO2 capture and gas processing. His experience covers petroleum, inorganics, gas processing, electrolytes and polymers. At the ASPEN Project at MIT (1978-1981), he contributed to the design and development of the thermophysical-property system that is now a key component of the AspenONE software suite. At Air Products and Chemicals (1981-1997) he developed and applied physical-property packages for technologies such as LNG, air separation and polyvinyl acetate, and improved and managed computational-chemistry technology for materials development. At Aspen Technology (1997-2004), he developed modeling solutions for the fertilized industry (ammonia, urea, nitric acid and phosphoric acid) and served as the Aspen Properties Product Manager. Dr. Mathias has also worked at Intera Environmental Consultants (Houston, TX) and Stone and Webster Engineering Corporation, and served as an adjunct professor at Lehigh University (1987-1997). He has also taught chemical-engineering courses at the University of California, Irvine.

Dr. Mathias first joined AIChE as a student member over four decades ago, and was elected as an AIChE Fellow in 2015. He has four patents, over seventy five publications and over one hundred technical presentations. He has organized and chaired sessions at AIChE, ACS and other meetings. He is an Associate Editor of The Journal of Chemical & Engineering Data, and has been a member of the editorial advisory board of two journals: The Journal of Chemical & Engineering Data (1997-2004) and Industrial and Engineering Chemistry Research (1997-2001). He has served on the advisory board of the chemical engineering departments at four universities: University of Florida (1990-present), University of Illinois at Chicago (2004-present), Texas A&M University (2004-2006), and University of California, Irvine (2012-present). He has served on the Thermodynamics and Transport Properties committee of AIChE (1986-2002; Chair 1999-2000) and serves on the Joint ASME/AIChE Committee on Thermophysical Properties (2001-present, vice chair 2015-).
