My current research focuses on sound production and echolocation in bats and interaction with prey. Bats perceive their surroundings through echolocation and we study how their echocation signals are shaped by acoustic constraints, habitat, feeding behavior and interaction with eared prey. My aim is to advance our understanding of how bats actively adjust the acoustic features of their sonar to probe the environment and guide their behavior. Work in the field (Panama, Denmark) is combined with lab work.

Projects include research on emited sound intensity in temperate and tropical (whispering) bats and adaptive sound control according to behavioral context. We do comparative studies of four species to correlate face and ear morphology to sonar beam directionality and we aim to use this for the construction of biomimetic bat-robots. Further, we study hearing and sound production in nocturnal moths, the prey of bats. Some projects focus on comparing sonar in air (bats) and water (toothed whales).
