In 2015-2016, I'm a visiting assistant professor and a Brown Fellow at Stanford University, working with Maneesh Agrawala. I recently finished my Ph.D. in EECS at MIT, working in the User Interface Design Group in CSAIL, advised by Rob Miller and Krzysztof Gajos. During gradschool, I was supported by the Samsung Scholarship.
As a Human-Computer Interaction (HCI) researcher, I build interactive systems powered by large-scale data from users. My Ph.D. thesis introduces learnersourcing, in which learners collectively generate novel content and interfaces for future learners while engaging in a meaningful learning experience themselves. Learnersourcing uniquely combines crowdsourcing, social computing, content-based video analysis techniques, and learning science. My research demonstrates that interfaces powered by learnersourcing can enhance content navigation, create a sense of learning with others, and ultimately improve learning.
