I am a second-year computer science PhD student at Vislang Lab in Rice University, advised by Prof. Vicente Ordóñez. Prior to this, I obtained a BSc degree (First Class Honours) from City University of Hong Kong, where I had the privilege of working with Prof. Rynson W.H. Lau and Prof. Antoni B. Chan.

My primary research interests lie in computer vision, with a focus on efficient algorithms under less or multimodal supervision. I am particularly interested in leveraging knowledge from neuroscience and cognitive psychology to develop concise, efficient, and interpretable algorithms achieving human-level intelligence in versatile tasks.

As a PhD student, I am always excited to collaborate with other researchers and explore new fields. Do not hesitate to reach out if you are interested!
