António Amorim, a retired professor at the Faculty of Sciences of the University of Porto since 2022, and a researcher at the University of Porto’s Institute for Research and Innovation in Health (i3S), where he led the “Population Genetics and Evolution” research group, passed away this Thursday at the age of 72. Professor António Amorim was a world-renowned population geneticist, the author of more than 600 published scientific papers and one of the most cited in the world in the field of forensic sciences. He collaborated with the former Department of Anthropology at the University of Coimbra, where he taught Human Population Genetics in 1990-91, and has been a friend and collaborator of the CIAS Genetics Group ever since, having co-signed the publication of several scientific papers. CIAS therefore expresses its sorrow at the death of Professor António Amorim, which it considers to be a huge loss for population genetics in Portugal.
