Large collections of open-source repositories such as GitHub have provided our research community a unique opportunity to mine for common application programming interface (API) usage patterns across vastly disparate codebases. Despite almost two decades of mining repositories research, there is no easy way for a user to understand the commonalities and variances among a massive number of related code examples. Further, the usability of mined specifications is an insufficiently researched topic. In this talk, I discuss a few examples of our recent work on improving the usability and information delivery of mining software repositories research. In particular, I discuss how we use the patterns mined from 380K Java repositories on GitHub to investigate API misuse on Stack Overflow, a popular online Q&A forum for software development. I will also showcase a new research thrust between software engineering and human computer interaction to design a novel interactive visualization interface that summarizes hundreds of code examples in one synthetic code skeleton.

Between January 2009 and August 2014, she was an assistant professor in the Department of Electrical and Computer Engineering at the University of Texas at Austin. She also spent time as a visiting researcher at the Research in Software Engineering (RiSE) group at Microsoft Research during the summer of 2011 and 2014. She ranked No. 1 among all engineering and science students in KAIST in 2001 and received the Korean Ministry of Education, Science, and Technology Award, the highest honor given to an undergraduate student in Korea in 2001.

Her research focuses on software engineering, specifically on software evolution. She develops software analysis algorithms and development tools to improve programmer productivity and program correctness. She also conducts user studies with professional software engineers and carries out quantitative, statistical analysis of open source project data to allow data-driven decisions for designing novel software engineering tools.
