I'm Safwat Hassan, an Assistant Professor

Currently, I am working as an assistant professor at the University of Toronto (Canada). I completed my Ph.D. degree at Queen’s University in the Software Analysis and Intelligence Lab (SAIL) under the supervision of Prof. Ahmed E. Hassan.

Before starting my Ph.D., I worked as a software engineer for ten years in different corporations like the Egyptian Space Agency (ESA), Hewlett Packard (HP), Electronic Data Systems (EDS), VF Germany (outsourced by HP), and Etisalat.
