Tristan Geiller, PhD

The goal of the Geiller Lab is to find a mechanistic explanation for how the brain learns, stores, and uses everyday life experiences to guide future behaviors. To answer this question, they establish links between the organization and function of cortical circuits in the mouse, with a particular focus on the hippocampus. Geiller's research group employs and develops state-of-the-art techniques, including in vivo functional imaging, electrophysiological recordings, manipulation of neural activity with single-cell precision, as well as molecular tools for accessing and identifying specific neuron types.

Tristan Geiller obtained a Master of Science and Engineering in Materials from France before moving to Seoul, South Korea, to complete a graduate degree in Neuroscience / Psychology at Korea University. After a postdoc at Columbia University, Tristan joined the faculty of the Department of Neuroscience at Yale School of Medicine in 2024 and is a Wu Tsai Institute Investigator. Outside the lab, you may find Tristan on the tennis courts or road cycling into headwinds.
