Sheng Li

Hi! I am Sheng Li. I am currently a final-year Ph.D. student in Department of Computer Science at the University of Pittsburgh, advised by Dr. Xulong Tang. I received my B.E. degree in Software Engineering from Sichuan University, China, in 2020.

My research focuses on designing and optimizing Efficient Machine Learning Algorithms and Systems, spanning applications in Image/Video Generation, RAG-enabled LLM Serving, Self-supervised Contrastive Learning, Supervised Model Training, and 3D Gaussian Splatting. My research targets platforms ranging from large-scale cloud clusters to resource-constrained edge devices.
