Ofer Pasternak

I am a PhD student at the School of Computer Science of the Tel Aviv University, Israel. My advisors are Dr. Nir Sochen and Prof. Nathan Intrator. I also work at the Functional Human Brain Mapping Unit, Tel-Aviv Sourasky Medical Center, Israel. I work there under the supervision of Dr. Yaniv Assaf.
