​Harald W. Krenn is an Associate Professor at the Department of Integrative Zoology at the University of Vienna (Austria), where he graduated in Zoology and Botany. His current research focuses on the evolutionary morphology of insect mouthparts, integrating new methods of functional morphology with feeding behaviour and ecology under evolutionary perspectives. He is particularly interested in interdisciplinary research on flower-visiting insects, which also involves fieldwork in the Austrian Alps, Neotropical rainforests and the Cape Floristic Region of South Africa.
