limits2vision-iRTG will launch the “Visiting Researchers” program with Christian Damsgaard, Associate Professor in the Department of Biology, Zoophysiology at Aarhus University in Denmark.
On Tuesday 12 May at 2 p.m., Damsgaard will give a talk on “The anaerobic metabolic ecosystem of the bird eye” in the HNO Lecture Hall at the Institute for Ophthalmic Research in Tübingen. He will also be available for discussions and lab visits. Save the date!

Prof. Damsgaard is a comparative and evolutionary physiologist who investigates the mechanisms of gas exchange in vertebrates, particularly in relation to acid–base regulation and neural function. Using the retina as a model system, he combines cardiorespiratory and electrophysiological techniques with OMICs approaches to study how oxygen diffusion shapes metabolism and tissue function across spatial gradients. His work integrates phylogenetically informed, multi-species methods to reveal how respiratory systems and their physiological trade-offs have evolved over macroevolutionary timescales.

Prof. Damsgaard’s most recent publication is highly relevant to the questions addressed in the limits2vision programme: Damsgaard C, et al., Oxygen-free metabolism in the bird inner retina supported by the pecten.  Nature, 650: 657–663, 2026. doi:10.1038/s41586-025-09978-W. PMID: 41565811.
