Tianao Li
Student Track: Interfaces
Research Area: Computational Imaging, Computational Photography, Computer Vision
Advisor(s): Alexander, Emma
Cohort: September 2023
Expected Graduation Date: June 2028
Research Statement: My research interest is in the field of computational imaging and photography, which lies at the intersection of optics, signal processing, computer vision, and machine learning. Specifically, I study how generative priors, scene representations, and physics-based forward modeling can advance imaging — turning ill-posed measurements into faithful reconstructions of the world.

Yanzhi Li
Student Track: Systems
Research Area: Networking
Advisor(s): Kuzmanovic, Aleksandar
Cohort: September 2021
Expected Graduation Date: 2026
Research Statement: My research interests are general Networking topics including cloud computing and virtualization. I want to develop networked systems that focus on three perspectives: reducing latency, preserving privacy and utilizing edge servers. Currently, I am working on reducing web page loading time by moving the process of fetching web content from the remote servers to the edge servers.

Haozheng Luo
Student Track: Artificial Intelligence
Research Area: Foundation Model
Advisor(s): Yan, Chen
Cohort: September 2022
Expected Graduation Date: June 2027
Research Statement: My research focuses on the learning aspects of AI—to enable efficiency (e.g., quantization robustness [ICML '24] [ICML '25] and parameter-efficient fine-tuning [ICML '25] [NeurIPS '25]) and safety ([USENIX Security '25]) in large language models ([ICLR '25]), large reasoning models, and multi-modal ([ES-FoMo@ICML '25]) environments.
I am interested in:
Large Foundation Models:
Comprehensible Foundation Models, integrating modern Hopfield networks. [ICML '24]
Responsible Foundation Models: encompassing jailbreaks, adversarial attacks, and risks associated with scientific foundation models. [USENIX Security '25] [arXiv] [MemFM@ICML '25]
Accessible Foundation Models, incorporating PEFT, quantization, and outlier removal for efficient training and enhanced quantization robustness. [ICML '24] [ICML '25] [ES-FoMo@ICML '24] [ES-FoMo@ICML '25]
Actionable Foundation Models, featuring the Chain of Thought and Chain of Action methodologies. [ICLR '25] [arXiv]
Applications of Large Foundation Models, including Genomic Foundation Models and Human Mobility Foundation Models. [ICML '25] [Information Systems (2025)] [HuMob@SIGSPATIAL '24] [ES-FoMo@ICML '25] [NeurIPS '25]
Memory retrieval, memory-enhanced models, and memory editing techniques. [MemFM@ICML '25] [arXiv]
I am also broadly interested in the various applications of AI, e.g., Human Mobility ([NeurIPS '25][HuMob@SIGSPATIAL '24]), AI4Sci ([ICML '25]), and AI4Finance.
