Thomas Koop is a Professor of Atmospheric and Physical Chemistry in the Faculty of Chemistry at Bielefeld University, Germany. He received his PhD in Chemistry in 1996 at the Max Planck Institute for Chemistry in Mainz. After a two-year postdoc at MIT in 1997-1998 he went to ETH Zurich in 1999, where he was awarded his Habilitation in 2004. In the same year he joined Bielefeld University. He is also a cofounder and executive editor of the journal Atmospheric Chemistry and Physics.
The Koop Research Group studies the kinetics of phase transitions in aqueous systems, both theoretically and in laboratory experiments. These include homogeneous and heterogeneous ice nucleation processes, deliquescence and efflorescence transitions of water-soluble crystalline materials, and vitrification processes of aqueous glasses. Another line of research is devoted to the kinetics of ice recrystallization in polycrystalline ice samples in the presence of ice growth inhibitors such as antifreeze (glyco)proteins and synthetic analogues. Koop and his group develop simple experimental methods, procedures for data analysis, as well as physicochemical parameterizations for use in theoretical models.
