Experience

Apple 2022.5 - 2022.9

Research Intern - Machine Intelligence

At Apple AI/ML, I worked on prototypes and features to improve the developer experience. Shipped improved Swift code completion in Xcode and designed an syntactic code search algorithm published at PLDI'24.

Microsoft Research 2020.5 - 2020.8

Research Intern
Worked with the PROSE team (mentored by Titus Barik) on improving developer productivity in Visual Studio Code. I interviewed developers to elicit their needs for code transformation tools in editors. Inspired by the empirical data and relevant work in program synthesis, I designed reCode, an interaction model for rapidly performing complex code transformation using the familiar find-and-replace experience, published at UIST'21.

Carnegie Mellon University, Research Experiences for Undergraduate 2017.5 - 2017.8

Research Assistant
Penrose is a system that automatically visualizes mathematics using two domain-specific languages: Substance and Style. Co-advised by Jonathan Aldrich, Keenan Crane, Joshua Sunshine, and Katherine Ye, I designed and implemented the Style language, and extended the Substance language to support functions and logically quantified statements.

Columbia University, Computer Graphics and User Interfaces Lab 2017.1 - 2017.5

Research Assistant
Worked with prof. Steven Feiner, on Cyber Affordance Visualization in Augumented Reality project. Developed a Microsoft Hololens application that visualizes the Columbia campus in AR environment.
