I am currently a senior research scientist at Intel Labs.
Broadly, My research focuses on the development of systems and modeling that help smart devices collect and reason about sensor data.
I am working on developing mobile sensing systems and machine learning techniques that can reason about human context, activities, and social interactions in the wild.
I built prototype mobile applications based on a variety of mobile platforms including smart phones, smart watches, fitness trackers, and IOT devices.
Results from my research have been published in a number of top conferences including Ubicomp, MobiSys, ISWC, Sensys, and AAAI. According to Google Scholar,
I have more than 7000 citations and my h-index is 25.
I received my Ph.D. degree from the Department of Computer Science at Dartmouth College. My Ph.D. advisors are Prof. Andrew T. Campbell and Prof. Tanzeem Choudhury. As part of my doctoral work, I created the SoundSense system, which is the first ubiquitous sound understanding system for smart phones. I hold bachelor and master degrees in Computer Science from Tianjin University, Tianjin, China.
I am serving as Associate Editor for IMWUT.
I have been Registrations Chair of Mobisys 2017, Posters/Demos Chairs of Mobisys 2014, PC member of IPSN 2017, Ubicomp 2015, IEEE MASS 2013, Nokia Mobile Data Challenge (MDC), and the MobiSense 2011.
