CDS Research Areas
The research focus of the group of Prof. Drewitz is probability theory. Prime research topics include the theory of percolation, random geometric structures, as well as transport processes in random media. Problems arising from these areas are investigated from a variety of points of view. In particular, techniques which also prove helpful in data science, such as concentration of measures phenomena and other tools from high dimensional probability theory, play a key role in their understanding.
Before joining the University of Cologne, Prof. Drewitz held positions as an ETH Fellow at ETH Zurich as well as a J.F. Ritt Assistant Professor at Columbia University.
Jointly with Prof. Dr. Joachim Krug they had been granted the UoC Forum "Classical and quantum dynamics of interacting particle systems” (2017–2019) and are currently running the BCoMP seminar series (http://www.mi.uni-koeln.de/main/Alle/Kalender/RegionaleSeminare/BonnCologneSeminar/index.php).
