About Me

I am an Arts & Science Postdoctoral Researcher at the University of Toronto under the supervision of Professor Dirk Bernhardt-Walther and Professor Michael Gruninger. I am also a cofounder of PenPlay and a advisory board member at the Dexign Studio . I obtained my masters and my Ph.D. in Computer Science from McGill University where I was a Research Assistant in the Shape Analysis Group of Center for Intelligent Machines at McGill University working under the supervision of Professor Kaleem Siddiqi. I also received my bachelors in Computer Engineering from Sharif University of Technology. While doing my Ph.D. at McGill University, I was awarded Clark SELF Scholarship where I completed a series of Mini-MBA courses known as EDC (Executive Development Course) during the Fall and Winter of 2018-2019. Moreover, I did an internship at NeuroRx where I worked as a research engineer.

Research

Broadly speaking, my research interests include computer and human vision, machine learning, and medical imaging. Specifically, I am interested in knowing how structured knowledge about the world arises through visual perception, and how visual features are linked to the rich details of meaning that humans naturally assign to visual information. In my work, I aim to use perceptual organization principles from human vision to better understand, exploit and then improve the capabilities of computer vision-based perception and recognition systems.
