My Research

I am a first-year Ph.D. student at the Software Evolution and Analysis Laboratory (SEAL) of the Computer Science Department at UCLA directed by Prof. Dr. Miryung Kim.

 

My research is focused on creating human-in-the-loop systems integrated into the development cycles. These systems aim to reduce both the cognitive load and the time developers spend on post-processing code analysis results compared to the baseline tools. In addition to creating such systems, I am also interested in seeing their empirical effects or those of other existing developer tools in software development activities.

"Assessing the Quality of GitHub Copilot’s Code Generation"

The introduction of GitHub’s new code generation tool, GitHub Copilot, seems to be the first well-established instance of an AI pair-programmer. GitHub Copilot has access to a large amount of open-source projects, enabling it to utilize more extensive code in various programming languages than other code generation tools. Although the initial and informal assessments are promising, a systematic evaluation is needed to explore the limits and benefits of GitHub Copilot. The main objective of this study is to assess the quality of generated code provided by GitHub Copilot. We also aim to evaluate the impact of the quality and variety of input parameters fed to GitHub Copilot. To achieve this aim, we created an experimental setup for evaluating the generated code in terms of validity, correctness, and efficiency. The results suggest that GitHub Copilot was able to generate valid code with a 91.5% success rate. In terms of code correctness, out of 164 problems, 28.7% were correct, while 51.2% were partially correct, and 20.1% were incorrectly generated. Our empirical analysis shows that GitHub Copilot is a promising tool based on the results we obtained, however further and more comprehensive assessment is needed in the future.
