After completing his bachelor's degree in bioprocess engineering (from 2011 to 2015), Christian Tewinkel started the in-depth M.Sc. program of chemical process engineering at the Technical University of Hamburg. At the beginning of 2018 he graduated with his master thesis "Model-based analysis of the influence of thermophysical properties on the minimum energy design of integrated reaction and rectification processes". Since July 2018, Mr. Tewinkel has been working as an external Ph.D. student at the Institute of Process Systems Engineering. He is particularly interested in the fields of thermal separation technology, process- and plant engineering and the treatment of process wastewater.

In his research, Mr. Tewinkel deals with the development of an efficient process for the biological treatment of heavily organically polluted industrial wastewater. The primarily experimental-based process development of the investigated biofilm technology focuses on the maximation of the surface- and time-specific conversion of dissolved organic compounds and on the scale-up from laboratory- to pilot-scale. For the parallel, theoretical consideration of operability and process stability, Mr. Tewinkel models the process behavior and validates the simulation results experimentally.
