Dr. Marie Carlén is a Professor of Neuronal Networks, with speciality in cognitive mechanisms and group leader at the Department of Neuroscience.

Marie received her Ph.D. in medicine from Karolinska Institutet in 2005. Her doctoral studies were conducted in the laboratory of Professor Jonas Frisén and focused on stem cells and neurogenesis in the adult brain and spinal cord. Marie went to the Massachusetts Institute for Technology (MIT), Boston, for postdoc studies in the laboratory of Professor Li-Huei Tsai at the Picower Institute for Learning and Memory. During her postdoc, Marie investigated how the activity of inhibitory interneurons expressing parvalbumin (PV) relates to cortical oscillatory activities and cognitive functions.

In 2010, Marie was recruited back to Karolinska Institutet. Her laboratory is investigating the cellular and circuit underpinnings of cognition, focusing on the prefrontal cortex.
