About Me
I am a senior computer vision researcher at Apple in Herzliya. I recently graduated with a Ph.D. in computer science from Technion, researching computer vision and machine learning under the supervision of Prof. Michael Elad. I am interested in inverse problems, generative models, representation learning, and diffusion models. I have also spent the 2022 summer as a research intern at Google Research in Tel Aviv.
Prior to my Ph.D. studies, I obtained my B.Sc. in computer science from Technion, summa cum laude, as the class valedictorian. I also worked as a research intern at Cornell Tech in New York City, and as a freelance web and app developer.
