Welcome~

Yujia Xie

I am a principle researcher at Microsoft Core AI. I work as an onsite engineer at OpenAI, serving as the bridge between the two company, and contribute towards both OpenAI models and Microsoft models (see our recent launch!).

Previously, I work in Microsoft Azure Language Pillars, landing language models to the cloud service, and also the Microsoft Azure Cognitive Service Research Team, doing research on the large-scale training of multimodal representation models.

I got my Ph.D. degree from Georgia Tech in 2021, advised by Dr. Hongyuan Zha and Dr. Tuo Zhao. Prior to Ph.D. study, I received a bachelor’s degree in 2016 in theoretic and applied mechanics at Special College of Gifted Young (SCGY), University of Science and Technology of China (USTC).
