About Me

I received my Ph.D. degree in Department of Computer Science and Engineering from Hong Kong University of Science and Technology (HKUST).

My research interests center on cloud computing and its intersection with machine learning, with a special focus on resource management and generative AI model serving (Text-to-Image and LLM).

Please feel free to contact me if you are interested in my research 🤝. I am open to potential collaborations.
