Rate My Professor Sönke Johnsen

Johnsen's research in visual ecology centers on the optical and visual adaptations of marine organisms, particularly transparency, camouflage, bioluminescence, and perception in UV and polarized light in the open ocean. His studies integrate mathematical modeling, behavioral experiments, morphological analyses, and fieldwork involving blue-water diving, research vessel cruises such as in the Gulf Stream, and deep-sea submersibles. Notable contributions include highly cited works like "The Optics of Life: A Biologist's Guide to Light in Nature" (Princeton University Press, 2012), "Visual Ecology" (Princeton University Press, 2014, co-authored with Thomas W. Cronin, Justin Marshall, and Eric J. Warrant), "The Physics and Neurobiology of Magnetoreception" (Nature Reviews Neuroscience, 2005, with Kenneth J. Lohmann), and "Polarized Light as a Butterfly Mating Signal" (Nature, 2003). With over 11,900 citations, his scholarship has shaped fields including biophysics and deep-sea biology. Johnsen has been recognized with the Dean's Award for Excellence in Mentoring from Duke's Graduate School (2016), the PROSE Award for "Visual Ecology" (2015), and the Best Publication in 2020 award from the International Deep-Sea Biological Society for research on ultra-black camouflage. He has also contributed to public outreach, including consulting for the film Finding Nemo.
