Thomas Flatt - SNF Professor

Research group

The Flatt lab studies the evolution and mechanisms of life history and aging, using the fruit fly (Drosophila melanogaster) as an experimental model. For more details on our research see here.


Thomas Flatt is a Swiss National Science Foundation (SNSF) Professor at the Department of Ecology and Evolution at the University of Lausanne. Prior to his position in Lausanne, he was a permanent group leader at the Institute of Population Genetics at the Vetmeduni Vienna and a faculty member of the Vienna Graduate School of Population Genetics. He received his M.Sc. in population biology from the University of Basel in 1999 for work on phenotypic plasticity, supervised by Prof. Stephen Stearns and Prof. Richard Shine (Sydney). He earned his Ph.D. in 2004 for work on the hormonal regulation of life history traits and trade-offs from the University of Fribourg (supervised by Prof. Tadeusz Kawecki). After his Ph.D. he was a postdoctoral research fellow in the laboratory of Prof. Marc Tatar at Brown University (Providence, USA), sponsored by the SNSF and the Roche Research Foundation. In 2011 he co-edited a book on the genetic and physiological mechanisms of life history evolution (Oxford University Press 2011, with Andreas Heyland; link to book page). He has served on the editorial boards of several journals, including as a Deciding Editor for the Journal of Evolutionary Biology; currently he is an Associate Editor at Evolution and a contributing member of the Faculty of 1000. In 2012 he was a Fellow at the Wissenschaftskolleg zu Berlin, Institute for Advanced Study.

The Flatt group studies the evolution and mechanisms of life history and aging, using Drosophila as a model system. A major focus is on understanding the genomic basis of evolutionary changes in life history traits and lifespan in natural and evolved laboratory populations. Another focus is on the hormonal regulation of life history trade-offs (especially the trade-off between reproduction and lifespan) and the endocrine modulation of aging.
