Introduction

I am a PhD graduate from MIT CAD Lab and UID Group with a keen interest in developing software tools to improve design engineers' creativity and productivity. My work at MIT explored methods for improving source code editing—which can often be tedious and repetitive—using machine learning algorithm and novel user interface. I worked on a code completion system that can simultaneously complete multiple keywords at a time from abbreviated input (Abbreviation Completion). I also worked on source code editing based on a spreadsheet-like, cell-based text representation (Editable-In-Chunks). Before working on tools for software engineers, I also worked on tools for hardware engineers. I developed a visual programming environment for creating an integrated simulation of engineering analysis tools (Catalog Model Builder). I earned a bachelor's degree in mechanical engineering from Seoul National University in 2000. After graduating from the university, I joined a startup company called BonaVision in Seoul as a software engineer. I had a lot of fun there for 4 years working on various web applications and robotics software projects. In 2004, I decided to apply for graduate studies and was fortunate enough to make it into MIT. While at MIT, I enjoyed volunteering for MIT Korean Language Class as an instructor and a coordinator.
