Toomas Kivisild graduated as a Biologist and received his PhD in Genetics, from University of Tartu, Estonia, in 2000. He has taught courses on human evolution and population genetics at the University of Cambridge (2006-2018) and from 2018 at KU Leuven. He is interested in how genetic changes occur in the history of human populations. His recent work has focused on questions relating global genetic population structure with evolutionary processes such as selection, drift, migrations and admixture using evidence from modern and ancient genomes. He is a co-author of the 2 nd edition of ‘Human Evolutionary Genetics’ textbook and has led and co-authored in more than 100 peer reviewed papers on human population genetics.
