Mr. Johannes Lawen

I obtained my BSc degree in Biotechnology from Hamburg University of Applied Sciences in 2006, followed by my MSc degree in Process Engineering from Hamburg University of Technology in 2010. During my master’s studies, my focus was on the development of a species transport model. After graduation, I developed the transport model incrementally into an independent 3D turbulent hydrodynamic model, including at Texas A&M, followed by application in industry and academia.

Since 2026 I am a Ph.D. candidate at the Institute of Geo-Hydroinformatics of Hamburg University of Technology. My PhD research focuses on modeling riverine hydrodynamics, heat exchange, and evaporation.
