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