Qi Qi @ META, UI
 |
Senior Research Scientist |
Short Bio
I am a Senior Research Scientist at Meta Superintelligence Labs, working on post-training. I have received Ph.D. degree in the Department of Computer Science from the machine learning and optimization group of University of Iowa under the supervision of Prof. Tianbao Yang. Before joined UIowa, I received master degree from University of Science and Technology of China under the supervision of Prof. Thomas Weise and bachelor degree from Qingdao University of Technology.
