Dr. Jürgen Rarey is a physical properties and chemical process simulation specialist with a diploma in chemistry and Ph.D. in chemical engineering from the Technical University of Dortmund (Germany). Since 1989, he has had a permanent position at the University of Oldenburg in the group of Prof. Gmehling, later Prof. Wark. During that time, he also co-founded DDBST GmbH, a well-known provider of thermophysical property data and estimation methods. Since 2016, Jürgen has served as a faculty member at ChEPS-KMUTT, Thonburi (Thailand), where he teaches regular courses on chemical thermodynamics.

Besides his experimental and theoretical work, Jürgen Rarey has been teaching courses for academia and industry on chemical thermodynamics, process simulation, and chemical process development. Dr. Rarey has authored about 50 publications in international journals, four books of the DECHEMA Chemistry Data Series, and the textbook Chemical Thermodynamics for Process Simulation (Wiley, 2012 and 2018).
