Andreas Haarstrick has studied of Chemistry at the Technische Universität Braunschweig (1983 – 1989) and received his doctorate in 1992 in the field of biotechnological production and down streaming of biopolymers. Since 2006, he is Professor for Bioprocess Engineering at the TU Braunschweig. His research interests cover modelling biological and chemical processes in heterogeneous systems, development of models predicting pollutant reduction in and emission behavior of landfills, growth kinetics at low substrate concentrations under changing environmental conditions, and environmental biotechnology. Since 2012, he is the managing director of the DAAD exceed-Swindon project dealing with the sustainable water management in developing countries.
