I am a third-year CS PhD student at Yale University supervised by Rex Ying and Arman Cohan. My research interests are in machine reasoning. I was a PhD student of the late Dragomir Radev.

I completed my B.Eng Computer Science degree in Nanyang Technological University, Singapore where I worked with Prof. Shafiq Rayhan Joty on text summarization and text generation.
At NTU, I was awarded the Best Final Year Thesis Gold Medal.

I am open to academic collaborations and mentoring motivated undergrad/master’s students. Drop me an email if you are interested in having a discussion about research, Ph.D. life, summer internships and etc.
