Prof. dr. Astrid T. Groot is professor of Evolutionary and Population Biology at the Institute for Biodiversity and Ecosystem Dynamics (IBED), University of Amsterdam. Her central research question is how the evolution of sexual communication affects speciation, which she mostly investigates in noctuid moths. She investigates the effects of interacting species, ranging from plant-insect to predator-prey interactions, as well as the effects of temperature and light, on variation in sexual signals and responses within and between populations.
