Koen Verhoeven is an ecological geneticist at the Netherlands Institute of Ecology (NIOO-KNAW), Wageningen, The Netherlands. His research on plant adaptation uses genetic and genomic tools and applies them in ecologically relevant contexts in order to understand how plant populations respond to changing environments. One of his research interests is in ecological epigenetics: what role does epigenetic variation play in ecology and microevolution? In this research he is coordinator of the EPiDiverse Marie Curie European training network. Other topics of his ongoing work include genetic and ecological aspects of plant invasions, plant urban evolution and intraspecific variation in plant-microbiome interactions. Koen Verhoeven serves as executive vice-president of the European Society for Evolutionary Biology (ESEB) and is a board member of the Netherlands Society of Evolutionary Biology.
