Tobias Köppl is an applied mathematician. He received his PhD in 2015 at the Technical University of Munich. From 2014 to 2018, he was a postdoctoral researcher at the Department for Hydromechanics and Modelling of Hydrosystems of the University of Stuttgart. In December 2020, Dr. Tobias Köppl successfully completed his habilitation at the University of Stuttgart. At the moment he is working as a reseacher at the University of Hasselt. Prof. Dr. Rainer Helmig since the year 2000, Rainer Helmig is the head of the Department of Hydromechanics and Moeling of Hydrosystems at the Institute for Modelling Hydraulic and Environmental Systems (IWS) of the University of Stuttgart. His research is focused on developing numerical methods for coupling hydrosystem compartments and complex flow and transport processes as well as integrating data and hydrosystem models.Rainer Helmig is author of numerous articles and books.
