About Me

My research focuses on deep learning, computer vision and medical AI, in particular dynamic neural networks and efficient learning/inference of deep models in resource-constrained scenarios.

Recently, I am interested in directions related to Efficient/Dynamic Vision Language Model (VLM), Visual Generation, and scalable medical AI systems.

I'm also interested in fundamental machine learning problems, such as semi-supervised long-tailed learning and fine-grained learning.
