About

Jakob Christensen‐Dalsgaard is a leading figure in the biophysics of vertebrate hearing, with a career dedicated to unraveling how lizards—creatures with seemingly simple ears—achieve remarkable sound localization. His core research explores the mechanics of **pressure-gradient receivers** and **internally coupled ears**, demonstrating that lizards overcome their small head size and low-frequency hearing through extreme, direction-dependent eardrum vibrations, achieving up to 30 dB of directional sensitivity. This foundational work, detailed in his highly cited 2010 paper (77 citations), has profound implications for understanding auditory evolution. Christensen‐Dalsgaard is also a pioneer in **biorobotics**, translating biological principles into functional models. His "Braitenberg Lizard" (2009, 19 citations) and subsequent robotic platforms (2010, 2016) use real lizard ear mechanics to achieve continuous phonotaxis, effectively building a robotic ear that hears like a lizard. By bridging neuroethology and engineering, his work not only explains how these reptiles navigate a world of low-frequency sound but also inspires novel, bio-inspired auditory sensors. His 2019 synthesis (14 citations) cements his role as a key architect in the field, showing how biophysics directly informs robotic design.
