Dr. Erez Eitan is the chief scientific officer and founding scientist of NeuroDex, a startup biotechnology company committed to developing diagnostic tests for diverse neurological conditions. Dr. Eitan is a neuroscientist with over 30 publications in peer-reviewed journals and expertise in extracellular vesicles — small, membrane-enclosed spheres that can be secreted by neurons. He did his postdoctoral research at the National Institute on Aging (NIA), where he was among the first to study extracellular vesicles. Dr. Eitan published work on the role of extracellular vesicles in the spread of amyloid beta and alpha-synuclein. He also was part of the team that first used immunoaffinity isolation of extracellular vesicles from the blood as a biomarker for neurodegenerative diseases. Currently, as chief scientific officer at NeuroDex, Dr. Eitan is working on validating extracellular vesicle-based blood tests for neurodegenerative diseases, preparing and optimizing them for clinical use.
