Sebastian Schwindt

About

Dr sc. (PhD) Sebastian Schwindt (he/him) is a researcher focusing on hydraulic systems and morphodynamics at the University of Stuttgart (visit his institutional profile). He leads the hydro-morphodynamics group at the Institute for Modelling Hydraulic and Environmental Systems (IWS). His research embraces numerical analyses with data-driven techniques, four-dimensional connectivity, and ecohydraulics for river restoration.

He completed his Bachelor's (2010) and Master's (2012) studies in Environmental Engineering at the Technical University of Munich (Germany). After a detour into the private hydropower sector, Sebastian accomplished his doctorate in Civil Engineering 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 fluid-sediment-structure interactions and flood risk mitigation with minimmized longitudinal connectivity interruptions (download at epfl.ch).

Later, Sebastian pursued postdoctoral research at the University of California, Davis (USA), with Prof. Greg Pasternack. The emphasis of his postdoctoral research was on the lateral connectivity and ecohydraulic enhancement of the Yuba River (California, USA) based on remote sensing (lidar) imagery and numerical models.
