I am a first-year Ph.D. student with Shwetak Patel and Jennifer Mankoff in the Paul G. Allen School of Computer Science & Engineering at the University of Washington – Seattle.

Before joining UW, I obtained my Bachelor’s degree in computer science from the University of Massachusetts Amherst in 2018, where my advisor was Sunghoon Ivan Lee. While at UMass Amherst, I received a 21st Century Leaders Award, Rising Researcher Award, and Outstanding Undergraduate Achievements Award. 

I am interested in using wearable sensing, human-computer interaction and machine learning to advancing healthcare.

During my undergraduate studies, I spent a huge amount of effort to push the international community to engage various leadership experiences in the university.  I was the first international peer mentor in the residential life office and the first international student consultant in the department of information and technology. I worked in six different departments during the four years :p

I am also a big fan of NBA 🙂
