After many great years at Microsoft Research, I have moved to Google. Stay tuned…
My research interests are in mobile computing, virtual reality, augmented reality, cyber-physical systems, sensors, ubiquitous computing and applied machine learning. I received the Best Paper award in MobiSys 2015, the Best Paper nomination in MobiSys 2012, the Best Demo award in MobiSys 2014, and the Best Demo nomination in SenSys 2011. I serve as the PC chair of NetGames 2017 and as the General Chair of HotMobile 2016. My work has appeared in such places as TechCrunch, PC Magazine, GameSpot, Ars Technia, Slashdot, The Verge [1,2,3], Engadget [1,2], Yahoo and Wired. At Microsoft, I have contributed to Windows and Windows Phone, Xbox and HoloLens.
The main objective of my work is the pursuit of perception-aligned mobile systems. Human attention is a scarce resource, but when available, it can also be wonderfully perceptive. My research seeks to answer the question:
Can we build mobile systems that align with the speed of human perception?
This is challenging as devices continue to shrink, increasingly enveloping and even embedding within the human body. A theme threaded throughout my work is interactive small data: how can inferences over personal data streams aid systems in interactive sub-second decision making? It turns out that not only are we amazingly perceptive beings, we are also creatures conditioned by habit. By appropriately leveraging statistical insights about our past behavior, mobile devices can in fact be well-positioned to service future needs, even at demanding interactive line rates.
