Prof. Dr. Hans Rudolf Fries


Chair of Animal Breeding
Professor emeritus since April 1, 2021

Academic Career and Research Areas

Prof. Fries researches the molecular genetics of the characteristics of farm animals. The goal is to shift breeding selection from the phenotypic to the genomic level. The focus lies on characteristics that are difficult to manage with conventional breeding.

After studying agricultural science at the Swiss Federal Institute of Technology (ETH) in Zurich, Prof. Fries went on to complete his doctorate there. Grants awarded by the Swiss National Science Foundation allowed him to conduct research at the Roman L. Hruska U.S. Meat Animal Research Center (1983) and Yale University (1984/85). Prof. Fries completed his lecturing qualification at ETH in 1993. Prior to becoming a professor at TUM (1995), he was an assistant professor and lecturer at ETH.
