Senior Manager, Optical Physiology

Jérôme Lecoq joined the Allen Institute in 2015 to lead efforts in mapping cortical computation using in vivo two-photon microscopy in behaving animals. He brings 10 years of experience in in vivo microscopy working with rodents. Prior to joining the Allen Institute, Lecoq was a postdoctoral scholar in Mark Schnitzer’s group at Stanford University, where he developed novel imaging methodologies to monitor large neuronal populations in the visual cortex of behaving mice. Lecoq received a Ph.D. in Neuroscience from the Pierre and Marie Curie University in Paris and an M.S. in Physics from ESPCI ParisTech, a French multidisciplinary engineering school.

Research Interests

Understanding how the cortex works will require building complex models that capture the essence of its computational principles. To test each of these models, we need datasets that appropriately capture the dimensionality of all the phenomena we want to understand. I seek to generate the datasets that will allow us to test decades-old ideas on cortical function. What are the roles of the different cortical layers? How do multiple brain areas collaborate to bring about cortical computation? Using a combination of high-throughput neuronal population recordings via optical imaging and careful experimental design, I hope to alleviate a generic problem in neuroscience: overfitting.
