Hi, I am a Ph.D. student at Harvard-MGB AIM, advised by Hugo Aerts Ph.D. and Danielle Bitterman MD. I am affiliated with Boston Children's Hospital Computational Health Informatics Program (CHIP) and we fortunately work closely with Guergana Savova Ph.D. and Tim Miller Ph.D.

My research interests are Natural Language Processing (NLP), with a focus on clinical translational studies, and bias/safety measures in generative models.

During COVID-19, I graduated with M.S. in Computational Linguistics from Brandeis University, where I was fortunate to be advised by Professor Nianwen Xue Ph.D. where I fully explored my interests and met many wonderful people and friends.

Before Brandeis, I spent 4 years as an undergraduate in Math, Japanese and Linguistics at St. Olaf College, really enjoyed my liberal arts education, click here if you want to learn more about my undergrad I'm a button.

During my free time, I do dragonboat, kyudo and play basketball! I also love history and e-sports.

Don't hesitate to email me if you are interested in research opportunities or want to collaborate.
