PhD student in Computer Science at Western University
I am a PhD student in Computer Science at Western University, supervised by Dr. Pingzhao Hu. My research lies at the intersection of machine learning, computer vision, and biomedical applications, with a focus on data-efficient and interpretable AI systems for rare disease diagnosis, medical imaging, and multimodal clinical decision support. Before joining Western University, I received my Bachelor of Computer Science degree at 2024 from the University of Waterloo.
