Tianyao Shi (史 天尧)

Purdue University

I am currently a member of Prof. Yi Ding’s STYLE group. I became a PhD student at Purdue University in August 2024.

I obtained my Bachelor’s degree of Computer Science and Master’s degree in Electronic and Information Engineering from Shanghai Jiao Tong University in June 2021 and March 2024, respectively.

My research interest focuses on Suistainability of Computing, e.g., Energy- and Carbon-Efficient Data Center Operation and LLM Serving. I used to work on Data Mining and Recommender Systems during my Master’s and Bachelor’s study, and led a project aimed at optimizing system efficiency of public cloud computing platforms.
