I just started my industrial career as a senior data scientist @ Visa Inc. My work is related to the development and research of LLMs and agent systems.
I got my Ph.D degree at the Information Science & Technology (IST) department of George Mason University (GMU), under the supervision of Dr. Kun Sun. Before that, I obtained a Bachelor of Engineering in Communication Engineering in 2016 and a Master of Engineering in Computer Science in 2019 from Nanjing University of Posts & Telecommunications (NJUPT).
