Bernhard Fink received his PhD in Biological Anthropology from the University of Vienna (Austria). He then moved to the University of Göttingen (Germany) where he held prestigious grants from the German Science Foundation (DFG) to investigate the social perception of human facial/body morphology and body movements, such as dance and gait. His work comprises the study of cross-cultural similarities and differences in human social perception, including research in pre-industrialized (small-scale) societies. Bernhard has worked extensively on digit ratio (2D:4D), a supposed proxy for prenatal androgenization. Together with John Manning (Swansea University), he examines 2D:4D relationships with sex-dependent traits across nations in a large sample from the BBC internet study.
