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.
