About

Dr sc. (PhD) Sebastian Schwindt is a researcher in river ecosystems and morphodynamics at the University of Stuttgart (visit his institutional profile). He leads the hydro-morphological modeling group at the Institute for Modelling Hydraulic and Environmental Systems (IWS). His research embraces numerical analyses, workflow automation, and optimization with Python, ecohydraulics, and ecosystem design. The focus of his latest works is on the optimization of (geospatial) data analyses, the accuracy of numerical models, and computational methods.
He completed his Bachelor's (2010) and Master's (2012) studies in Environmental Engineering at the Technical University of Munich (Germany). After a short detour into the private hydropower sector, Sebastian accomplished his doctorate at the Ecole Polytechnique fédérale de Lausanne (EPFL, Switzerland) from 2013 to 2017 under the supervision of Prof. Anton J. Schleiss and Prof. Mário Franca. His PhD thesis entitled Hydro-morphological processes through permeable sediment traps at mountain rivers provides new insights into sediment transport for landscape dynamics and flood risk mitigation in Alpine regions (download at epfl.ch).
Between 2017 and 2019, Sebastian pursued postdoctoral research at the University of California, Davis (USA), with Prof. Greg Pasternack. The emphasis of his postdoctoral research was on the ecohydraulic enhancement of the Yuba River (California, USA) based on aerial (lidar) imagery and numerical models.
