I’m a PhD student at CU Boulder advised by Prof. Danna Gurari. My research focuses on vision-language models that capture hierarchical object compositions for visual grounding and accessibility. I’ve also helped organize the VizWiz Grand Challenge, an annual CVPR workshop advancing accessibility research in computer vision.
Before starting my PhD, I co-founded RoastPic, a platform that helps coffee companies evaluate roast profiles through visual analysis. Outside of research, I enjoy climbing, skiing, exploring specialty coffee, and also contribute to open-source community.
