Short Bio

Hassan is a PhD student in Computer Science at York University, specializing in Computer Vision, with a particular emphasis on diffusion models and their applications in medical image analysis. His current research aims to enhance the performance and explainability of medical image classifiers through the use of synthetic data, thereby addressing key challenges in the healthcare field. He completed his Master’s degree at Sharif University of Technology in Artificial Intelligence, where he focused on semantic segmentation, 3D computer vision, and knowledge distillation. During his Master’s, He proposed a novel framework to improve point cloud semantic segmentation models in data-scarce scenarios by integrating additional modalities, such as images, and distilling their knowledge into a point cloud-based network. This work contributed to the development of more accurate and data-efficient models for 3D semantic segmentation.

Area of Research

  • Generative AI
  • Fairness of AI models
  • AI in medical imaging
