We are pleased to announce the second edition of the UNIL Summer School on Modelling for Evolutionary Biology. This is an intensive week of seminars, lectures, practical sessions, and collaborative work, aimed primarily at PhD students interested in using formal models in evolutionary ecology. We cover the fundamentals of invasion analysis and its links to population and quantitative genetics, and apply these tools to questions in social evolution, life-history evolution, and species interactions. The course is open to participants from any institution and we particularly welcome international students. Application deadline: 27 June 2026 Scholarship deadline: 15 May 2026 (covering travel and tuition for selected participants) Full details and programme available at: https://www.unil.ch/unil/en/home/menuinst/etudier/programmes-courts/summer-winter-schools/modelisation-pour-la-biologie-de-l-evolution-1.html With best wishes, Charles Mullon Département d’Écologie et d’Évolution Université de Lausanne (to subscribe/unsubscribe the EvolDir send mail to evoldir@evoldir.net)
