I am currently a 2yr Ph.D. student at UCLA Computer Science Department in Los Angeles, CA. I am happy to work with Deborah Estrin and Ramesh Govindan. Prior to joining CENS at UCLA, I received my M.S. in Information Networking from Carnegie Mellon University and B.S. in Computer Science from Korea Advanced Institute of Science and Technology. My main research interests are in ubiquitous computing, mobile systems, and machine learning. My current focus is on developing sensible localization techniques realizable on mobile devices, and addressing emerging chellenges when sensor data is continously collected, processed, shared by mobile devices.
Current Projects
iWas, an automatic daily location trace logger
iWas is a mobile service that continuously tracks user's indoor/outdoor locations and presents a colloquial places or collected representation of locations such as "Home", "My office", or "Joe's plummbing store" instead of a series of raw coordinates.
AndTracer, a service module for Android platform
AndTracer is a service module for Android that supports mobile applications to continously collect and share various sensor data in parallel. It optimizes sampling strategies in order to reduce power consumption while supporting various applications with different sampling requirements, and provides easy-to-use interfaces.
