Who is Peter Hegemann?
In short
Peter Hegemann is a German biophysicist and the 2026 Nobel Prize winner in Physiology or Medicine. He is currently in the news for receiving this award alongside Karl Deisseroth and Georg Nagel for their pioneering work in optogenetics.
Who they are now
He serves as the Hertie Senior Research Chair for Neurosciences and is a professor of Experimental Biophysics at Humboldt University of Berlin. His work focuses on the biological mechanisms of light-sensitive ion channels.
Why they are in the news
He is trending because he was recently announced as a recipient of the 2026 Nobel Prize in Physiology or Medicine for his discoveries in optogenetics.
An example of their work
He discovered channelrhodopsin, which is a type of ion channel that can be controlled by light. This discovery allowed scientists to use light to switch specific groups of neurons on or off, creating the field of optogenetics.
