Fourth-Year PhD Student, University of Washington

I am a fourth-year CSE Ph.D. student at University of Washington. I’m advised by Amy X. Zhang and part of the Social Futures Lab. My research sits at the intersection of social computing and human–AI collaboration. I design tools that empower non-technical users to shape and control the algorithms that shape their online experiences. I am especially interested in using LLMs, end-user development techniques, and interactive machine learning to make algorithmic systems more understandable, customizable, and aligned with human intent.

I interned at Google Search (2024-2025), working with Otilia Stretcu and Ranjay Krishna on empowering domain experts to train image classifiers for complex subjective concepts. I also spent a summer with the AI & Society group at Microsoft Research (2023), collaborating with Scott Counts to understand the challenges knowledge workers face when interacting with generative conversational agents. Before coming to UW, I worked as a research assistant at Social AI Group at Carnegie Mellon University, where I was co-advised by Professors Haiyi Zhu and Steven Wu. I was also fortunate to be part of CMU DIG lab and advised by Professor Adam Perer.

I am always happy to chat about research and collarabote. Feel free to drop me an email :)
