At CHI 2008, we presented the first field study of UbiFit, a system that uses mobile phones and wearable wireless sensors to improve fitness. Our Ubicomp 2007 paper applies machine learning + wearable accelerometers to recognize free-weight exercises. Discovery Channel covered our innovation in "A Personal Trainer, in the Palm of Your Hand". (See my publication list for the full papers)

In 2007, I joined a stealth-mode startup, Ludic Labs, in San Mateo, California, founded by the founding team of Inktomi. At Intel Research Seattle, I led two mobile phone/ubicomp projects that led to publications at Ubicomp (4), MobiSys (2), UIST, HotOS, and HotMobile:

My mobile phone research focuses on rapid development of context-enhanced apps on cell phones and novel uses of personal context such as location, physical activities (e.g. running, cycling), and communication (e.g. phone calls, email, SMS).

During my years at UC Berkeley, my advisor was Prof. Eric Brewer, co-founder of Inktomi. I also worked closely with Prof. Dave Patterson, currently the ACM President, Prof. Armando Fox, and Prof. Marti Hearst on the following projects:

  • ROC - recovery-oriented computing.
  • Ninja - infrastructure for scalable, composable Internet services.
  • Cha-Cha - exploiting hyperlink structure to provide search result context.
