About

I am a second-year Ph.D. student in the Paul G. Allen School of Computer Science & Engineering at the University of Washington – Seattle. I am advised by Shwetak Patel and Daniel McDuff.  

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 Achievement Award. 

My research interest lie in the intersection of on-device machine learning, sensing and health — bringing machine learning to IoT and embedded medical devices to advance the state-of-the-art healthcare 🙂

Misc.

During my undergraduate studies, I spent a huge amount of effort to push the international community to engage various leadership experiences at 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 🙂
