I am a third-year Ph.D. student in the Department of Computer and Information Science at the
University of Pennsylvania, working under the guidance of Prof.
Andrew Head.
My research focuses on human-AI interaction and software engineering, with a focus on
using large language models (LLMs) to enhance code
comprehension. In projects like Ivie, I investigate how AI can
improve the understanding of generated code by providing lightweight explanations, particularly for
APIs
and programming patterns. Currently, I am working on a project that addresses
difficult programmer questions and aims to create new types of software
engineering agents.
My earlier work, including ExampleNet and ParaLib, developed visualization
tools to support
decision-making and workflow improvements for neural networks and programming environments.
Prior to my Ph.D. studies, I completed my master's in Computational Science and Engineering from
Harvard University, where I began exploring human-computer interaction
(HCI) for developers.
