Barak was awarded a Fulbright Postdoctoral Fellowship to pursue his research project titled “Wearable Medical Systems as a Source of Personalized Closed-Loop Therapies for Chronic Diseases". The research aims to explore selective conversions of chemical and biological recognition events into useful electrical signals, with the objective of developing flexible and stretchable bioelectronic devices for non-invasive on-body sensing and drug delivery. This research direction holds tremendous promise for revolutionizing healthcare in the future, offering personalized disease management and enhanced preventive care.

Barak completed his Ph.D. in the Faculty of Mechanical Engineering at Technion-Israel Institute of Technology. Under the supervision of Professor Gilad Yossifon. His Ph.D. research focused on studying micro/nano-fluidics and involved both fundamental investigations of electrokinetic transport processes within the nano and micro scales, as well as application-oriented studies aimed at developing novel tools and devices.

Barak was awarded several scholarships during his studies, including the Gutwirth and the Russel Berrie Nanotechnology Institute Scholarships, in addition to awards for his research contributions.
