Associate Professor Lasse Jakobsen primary research interest is sensory matched filtering, how irrelevant information is filtered away already at the sensory reception stage, speeding up processing-time considerably because the brain does not have to evaluate irrelevant information. He focuses on bat echolocation as a model because the bats’ active sensing (echolocation) gives unprecedented insight into such filtering.
Further, Lasse Jakobsen is very interested in how the concurrent evolution of echolocation and flight has shaped the fundamental framework for bat echolocation; flight and echolocation has evolved together over the last 65 million years, and as such echolocation has evolved specifically to guide flight.
In the Bat Echolocation Lab, we approach these topics using state of the art recording platforms; multi-microphone arrays and high-speed stereo video for 3D reconstruction, in combination with computational modelling. We utilize highly controlled laboratory experiments in our large indoor flight room and specially constructed wind-tunnel, to uncover fundamental mechanisms of echolocation, and combine this detailed knowledge with field studies using multi-microphone arrays, both stationery and drone-borne, to encompass the entire natural repertoire.
