Welcome to my website!

I am an Applied Scientist in Amazon AI, UK. I obtained my PhD in School of Computer Science and Engineering (SCSE), Nanyang Technological University (NTU), Singapore, advised by Prof Aixin Sun. Before my PhD, I received B.S. and M.S. (advisor: Prof Mun Y Yi) in KAIST, South Korea, in 2014 and 2016, respectively.

My research interests are information extraction, information retrieval, and biomedical NLP. At the moment, I am working on relation extraction with the focus on data generation and representation learning.
