PhD Student/Research Scientist Intern

UCL NLP

Google DeepMind

I am a second-year PhD student at UCL and a part-time research scientist intern at Google DeepMind, splitting my time between the two organizations during the course of my PhD. I am co-advised by Prof. Pontus Stenetorp and Prof. Sebastian Riedel at UCL NLP Group. I obtained my Master’s degree at Kim Jaechul Graduate School of AI, KAIST, under the guidance of Prof. Minjoon Seo at Language & Knowledge Lab. Prior to this, I was a research engineer at Naver Clova. My research interests lie in the ways to understand and enhance the reasoning ability of NLP/ML systems. Curiosity drives me, and I am happy to follow wherever it leads me.

I have suffered from severe RSI (Repetitive Strain Injury) on all my fingers developed from keyboard overuse from Jan 2021 to July 2022; during this period, I could not type anything without seriously aggravating nerve pain. Thankfully, in July 2022, the RSI finally began to be healed through numerous sessions of TPIs (Trigger Point Injections) on my arms by a very skillful doctor and I could restart leading a research project in August 2022. I plan to post on my homepage someday about what have been helpful for my treatment, in case it is helpful for others suffering from RSI as well.
