About Me
Know Me More
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.

Research
What I Do?
Users’ Feedback
We proposed approaches that help app developers proactively spot buggy releases and deploy fixes for such buggy releases.
Developers’ Common Practices
We studied the common practices of delivering main features in mobile apps, such as the patterns of integrating ad libraries.
Performance Analysis
We are collaborating with IBM to provide approaches to enhance the performance of software systems.
App Design
We propose approaches to design mobile apps with a high-quality user interface (UI).
Rapid Releases
We propose approaches to help developers perform rapid releases (without impacting their apps' perceived quality).
Developers’ Interactions
We analyzed developers’ interactions using development communication platforms, such as the Gitter platform.
