I am a visiting postdoc at Princeton University advised by Prof. Danqi Chen and also a postdoctoral researcher at Korea University. My research area is based on natural language processing and deep learning. Specifically, I'm interested in learning generalizable text retrieval with dense vectors (i.e., dense retrieval) and tackling challenges in biomedical NLP. I was a PhD student at Korea University advised by Prof. Jaewoo Kang. During my PhD, I did an internship at NAVER Clova where I spent my time developing BioBERT and DenSPI.
