I am currently a postdoctoral fellow working with Prof. Eero Simoncelli at the Flatiron Institute. My research interests include visual representation learning, inverse problems, information theory, and generative modeling.

Previously, I completed my Ph.D. in Computer Science at the Technion - Israel Institute of Technology, where I worked with Prof. Michael Elad and Prof. Tomer Michaeli. My doctoral research focused on the theoretical and practical aspects of image restoration and compression techniques that rely on generative models.
