Biography

Chen Gao is now a Faculty Member (Research-track AP) of BNRist, Tsinghua University. He obtained his Ph.D. Degree (advised by Prof. Yong Li and Prof. Depeng Jin) and Bachelor’s Degree from the Department of Electronic Engineering, Tsinghua University in 2021 and 2016, respectively. His research primarily focuses on data mining (recommender system and spatio-temporal data mining), large language model, embodied agent, etc., with over 60 papers in top-tier venues (50+ CCF-A), attracting over 4,000 citations.

Advertisements (long-term effective): I am seeking self-motivated interns (undergraduate or graduate) and collaborators to conduct research on data mining (recommendation and spatio-temporal data mining), large language models, embodied agent, etc. with us remotely or at Tsinghua. Our interns have good record of publishing first-author papers in CCF-A conferences/journals. Our team is also actively hiring Postdocs/PhD/Master students. Feel free to contact me via email if you are interested.
