Prof. Dr. Jürgen Geist

Academic Career and Research Areas

As part of his research, Prof. Geist (b. 1977) develops system biology models for chronological and spatial distribution of biodiversity in water ecosystems which integrate molecular biology and ecology approaches. Focus is placed on the quality of the aquatic habitat, genetic and demographic structures of fish and mussel populations, aquatic food webs and the development of stress biomarkers to indicate pollution in water bodies.

After studying agrobiology at TUM and completing his doctorate in genetics and ecology (2005), he received a postdoctoral grant to attend the University of California Davis, USA. He became junior professor of functional aquatic ecology and fish biology in 2008. After qualifying as a lecturer in aquatic ecology (2010), Prof. Geist was appointed to the Chair of Aquatic Systems Biology at TUM in 2010.
