about

I'm a Ph.D. candidate at University of California, San Diego. I work on programming tools advised by Haijun Xia. I completed my undergraduate at the University of Toronto in Computer Science where I interned at Dynamic Graphics Lab under Prof. Daniel Wigdor, conducting research in immersive analytics and interaction design.

Taking ASCII Drawings Seriously: How Programmers Diagram Code

A description of the content and use of ASCII drawings across large open-source codebases.

CHI 2024: Conference on Human Factors in Computing Systems.

CrossCode: Multi-level Visualization of Program Execution

Programmers reason about code across multiple levels of abstractions. Can we design a program visualization system that can change its level of abstraction according to the programmers’ needs?

CHI 2023: Conference on Human Factors in Computing Systems.

Structuring Collaboration in Programming Through Personal-Spaces

Can we create a pedagogical tool for collaborative programming that balances both agency and interdependence?

DataHop: Spatial Data Exploration in Virtual Reality

Stepping into a museum or a cultural exhibition instills a desire within us to explore new topics and cultures. What if we could create a similar spatial structure for visualizing complex and otherwise difficult to approach datasets? In this work, we explore meaningful layouts and organizational schemes for arranging one’s data analysis steps in the virtual environment.

UIST 2020: ACM Symposium on User Interface Software and Technology.

Plane, Ray, and Point: Enabling Precise Spatial Manipulations with Shape Constraints

A common complaint of high-degree of freedom input is that it can lead to unaligned and askew content. We looked into addressing this by enabling dynamic mappings of input degrees of freedom to manipulation axes.
