Thomas Flatt is Professor of Evolutionary Biology in the Department of Biology at the University of Fribourg. His research interests are the genetic and genomic basis of adaptation, population genetics, and the evolution of life histories and aging, with a focus on the mechanisms underlying trade-offs between fitness components. Most recently, his work has focused on the role of chromosomal inversion polymorphisms in adaptation. Thomas received his M.Sc. from the University of Basel in 1999 (supervised by S.C. Stearns), for work done at the University of Sydney with R. Shine, and his Ph.D. from Fribourg in 2004 (supervised by T. J. Kawecki). Between 2004 and 2008, he was a postdoctoral fellow at Brown University with M. Tatar and a visiting postdoc with N. Silverman at UMass Medical School, funded by fellowships from the Swiss National Science Foundation (SNSF) and Roche Research Foundation. Prior to taking up his position in Fribourg in 2017, he was a SNSF Professor in the Department of Ecology & Evolution at Lausanne (2012-17), a Fellow at the Wissenschaftskolleg Berlin (2012), a faculty member of the Vienna Graduate School of Population Genetics and a tenured group leader at the Institute of Population Genetics in Vienna (2009-12). Between 2018 and 2021 he held a DFG Mercator Fellowship and Visiting Professorship at the University of Münster. Together with Josefa Gonzalez (Barcelona) he co-leads the European Drosophila Population Genomics Consortium (DrosEU). He currently serves as a member of the editorial board of the Proceedings of the Royal Society B and as an elected member of the National Research Council of the Swiss National Science Foundation.
