About Dionisios G. Vlachos

Dionisios (Dion) G. Vlachos is the Unidel Dan Rich Chair in Energy Professor of Chemical & Biomolecular Engineering, a Professor of Physics and Astronomy at the University of Delaware, the Director of the University of Delaware Energy Institute (UDEI), of the UD node of the manufacturing institute RAPID, and the Catalysis Center for Energy Innovation (CCEI), an Energy Frontier Research Center (EFRC). He is the ExxonMobil Visiting Chair Professor, National University of Singapore, Singapore, 2018-2021.

Dion obtained a five-year diploma in Chemical Engineering from the National Technical University of Athens, Greece, in 1987, and his M.S. and Ph.D. from the University of Minnesota in 1990 and 1992. He spent a postdoctoral year at the Army High-Performance Computing Research Center in Minnesota. Dr. Vlachos joined the University of Massachusetts as an assistant professor and promoted to an associate professor in 1998. He joined the University of Delaware in 2000. He was a visiting fellow at Princeton University in 2000, a visiting faculty member at Thomas Jefferson University and Hospital in 2007, the George Pierce Distinguished Professor of Chemical Engineering and Materials Science at the University of Minnesota in 2007, the Allan and Myra Ferguson Professor of Chemical & Biomolecular Engineering, 2016-2020, and the Elizabeth Inez Kelley Professor of Chemical Engineering, 2009-2016.

He is the ExxonMobil Visiting Chair Professor, National University of Singapore, Singapore, 2018-2021. Professor Vlachos is the winner of the 2020 Irving Wender Award for Excellence in Catalysis from the Pittsburgh-Cleveland Catalysis Society, the 2016 Catalysis Club of Philadelphia Award, the R. H. Wilhelm Award in Chemical Reaction Engineering from AIChE (2011) and is an AAAS Fellow (since 2009). He also received an NSF Career Award and an Office of Naval Research Young Investigator Award.

Vlachos’ research focuses on circular economy and waste derivatization, multiscale modeling and simulation, distributed (bio)chemical manufacturing, process intensification and novel catalytic reactors, renewable fuels and chemicals, catalyst informatics and in silico materials prediction, and kinetic modeling. He is a pioneer of the multiscale modeling field and the introduction of fundamental research in biomass.

He is the corresponding author of more than 430 refereed publications, >26,600 citations, and an h factor of 90 (google scholar) and has given ~300 plenary lectures, keynote lectures, and other invited talks. Professor Vlachos has served as an executive editor of the Chemical Engineering Science journal and served on the editorial advisory board of ACS Catalysis, Reaction Chemistry & Engineering, Industrial and Engineering Chemistry Research, Applied Catalysis A: General, and others.
