I am a rising junior at Princeton University currently on leave. I am taking two years off for social service in Korea, so I am expected to graduate on May 2021. I am majoring in Mathematics and considering a minor in Statistics and Machine Learning.

I have been excited about Artificial Intelligence since I have started developing. My first project was a chess engine, and it has guided me through many challenging concepts. Now, I am taking online courses and working on personal projects using Keras with Tensorflow backend.

When I am not working, I enjoy playing Table Tennis and Badminton.
