Imagine the magnificent glaciers of Greenland, the eternal snow of the Tibetan high mountains, and the permanently ice-cold groundwater in Finland. As cold and beautiful as these are, for the structural biologist Kirill Kovalev, they are more importantly home to unusual molecules that could control brain cells’ activity.

Kovalev, EIPOD Postdoctoral Fellow at EMBL Hamburg’s Schneider Group and EMBL-EBI’s Bateman Group, is a physicist passionate about solving biological problems. He is particularly hooked by rhodopsins, a group of colorful proteins that enable aquatic microorganisms to harness sunlight for energy.

“In my work, I search for unusual rhodopsins and try to understand what they do,” said Kovalev. “Such molecules could have undiscovered functions that we could benefit from.”
