Prof. Eitan Okun, Ph.D., is a Full Professor at the Mina and Everard Goodman Faculty of Life Sciences and the Gonda Multidisciplinary Brain Research Center at Bar-Ilan University, where he also serves as Vice Dean for Research Resources Development. He received his Ph.D. in Biology from Bar-Ilan University in 2007 and completed his postdoctoral training at the National Institute on Aging (NIH, USA), before accepting an associate professor position at the Life Sciences faculty at Bar-Ilan University. He is the head of the Paul Feder Laboratory for Alzheimer’s Disease Research, which focuses on neuroimmunology and the mechanisms governing communication between the immune system and the brain.

His research aims to understand how immune cells, the meningeal immune system, and lymphatic vessels influence brain function during health, aging, and neurodegenerative disease. The laboratory investigates the role of neuroimmune interactions in Alzheimer’s disease and Down Syndrome-related cognitive decline, with a particular interest in how sex hormones and biological sex shape brain immunity and disease susceptibility. By combining fundamental and translational approaches, the lab seeks to identify novel therapeutic targets and strategies to promote healthy brain aging and improve outcomes in neurodegenerative disorders.
