PhD Student

Hi!

I'm a PhD student at USC Information Sciences Institute and Department of Computer Science. I work at the PLUS lab advised by Dr. Nanyun Peng.

My main research interest is natural language processing (NLP) and my recent research focus is developing a system that can learn how to organize events contained in unstructured information into generic event ontology which are able to benefit downstream event-focused analytics.

I received my bachelor's degree in Computing from The Hong Kong Polytechnic University in 2018 and I was an exchange student at the University of Maryland in 2016. I was fortunate to work at CUHK, UCSC, MIT and PolyU on dialogue systems, sentiment analysis, blockchain and educational tech.
