The profile picture of Dr. Vahdat Abdelzad

I am a researcher in computer science and engineering with experience in deep learning, deep computer vision systems, and software engineering. I have been a research associate at the University of Waterloo, collaborating with Prof. Krzysztof Czarnecki. In this role, I specialized in out-of-distribution detection, 3D object detection, and domain adaptation for autonomous vehicles, contributing to advancements in autonomous driving technology.
Before this, I completed a postdoctoral fellowship at the University of Waterloo under the supervision of Prof. Krzysztof Czarnecki. During my post-doc, I focused on Explainable AI (XAI), active learning, and uncertainty estimation for deep neural networks, further honing my expertise in cutting-edge machine learning techniques.
I have obtained my Ph.D. from the University of Ottawa, where I worked under the esteemed supervision of Prof. Timothy C. Lethbridge. My doctoral research centered on modularity for model-based software engineering, and I made significant contributions to the Umple project.
