About
Peter Hegemann is a pioneer in optogenetics and microbial sensory rhodopsins, whose foundational work has reshaped how neuroscientists control and observe neuronal activity with light. His research focuses on the molecular mechanisms of light-activated ion channels and pumps, particularly channelrhodopsins, which he co-discovered in green algae. Hegemann’s major contributions include elucidating the photocycle dynamics of rhodopsin-based voltage sensors like Archon2, an engineered variant of Archaerhodopsin 3 developed through robotic multidimensional directed evolution. His spectroscopic studies of Archon2 have provided critical insights into its absorption, emission, and thermal dynamics, enabling more precise voltage imaging in living cells. With over 30,000 citations across his career, Hegemann’s work has been instrumental in advancing optogenetic tools for non-invasive control of neural circuits. Notably, his discoveries have been widely adopted in both basic neuroscience and clinical research, earning him numerous accolades, including the 2020 Brain Prize. Hegemann’s legacy continues to inspire new generations of researchers exploring the intersection of photobiology and neurotechnology.
