Jens Kremkow is currently a group leader in the Neuroscience Research Center at the Charité - Universitätsmedizin Berlin, the Bernstein Center for Computational Neuroscience Berlin, the Institute for Theoretical Biology at the Humboldt-Universität zu Berlin and the Einstein Center for Neurosciences Berlin. He runs the Integrative Visual Neuroscience Lab and uses both computational and experimental approaches to study sensory systems in the brain. In his Ph.D. he worked together with Ad Aertsen (University of Freiburg, Germany) and Guillaume Masson (CNRS Marseille, France) and developed computational models to study how correlated excitation and inhibition in neuronal circuits provides a mechanism for sparse coding during natural vision. In his postdoc in the group of Jose-Manuel Alonso (State University of New York - College of Optometry, New York, USA) he studied the visual thalamus and cortex using in vivo experiments and models. One of his projects revealed the principles underlying sensory map topography in primary visual cortex. Following his stay in New York, he joined the lab of James Poulet (MDC Berlin) and Richard Kempter (Humboldt-Universität zu Berlin) as an independent postdoc to study cortical neuronal circuits in rodents.
