About Me

Hello! I am a Software Engineer (ML/NLP) at Cresta AI. I earned my Ph.D. degree in Artificial Intelligence from the Department of Electrical and Computer Engineering & Ingenuity Labs at Queen’s University in September, 2022. Prior to Queen’s, I obtained my Bachelor’s degree in the College of Computer Science from Nankai University.

My research interests lie in the area of natural language processing and deep learning. My long-term research goal is to build robust and efficient models that can understand natural language and perform reasoning.
