About me

I am a computational and cognitive neuroscientist interested in studying the mind, brain and mental diseases. I am currently a postdoctoral researcher at Princeton neuroscience institute, working with Nathaniel Daw. I completed my doctoral studies in cognitive neuroscience under supervision of Ivan Toni and Roshan Cools at Donders Institute. My background is control engineering and machine learning, in which I obtained my bachelor and master from University of Tehran.
