Jinhyuk Lee

Research Scientist at Google Research


I am a research scientist at Google Research. I was a visiting postdoc at Princeton University advised by Prof. Danqi Chen and also a research professor at Korea University. My research area is based on natural language processing and deep learning. Specifically, I'm interested in modeling efficient and generalizable retrieval for NLP. I received my PhD at Korea University advised by Prof. Jaewoo Kang.
