Biography

I work as a mobile context analytics researcher at Samsung Research America, Silicon Valley, where I research core technologies and build mobile systems focusing on mobile user context sensing and pattern mining, to enable highly personalized mobile devices.

Since joining Samsung Research in February 2012, I have worked as a technical lead in developing on-device pattern mining and prediction systems on smartphones, researched context-aware mobile power management, and developed a power-efficient sensor-based context recognition system on Android and Tizen smartphones.

Before Samsung, I graduated with a PhD in computer science from the University of Virginia in December 2011, advised by Professor John Stankovic and Professor Kamin Whitehouse.  My PhD research focused on building non-invasive sensor platforms for smart homes and using data from these sensors to perform unsupervised inference of resident activities, identities, and resource usage patterns.

I have broad interests in mobile sensing and computing, data mining, machine learning, cyber-physical systems, and ubiquitous computing. Check my recent and past publications for more information!
