Research

I work on applied computer vision for understanding real-world images and video. My prior projects explore ways to generate or augment training data for fine-grained classification, detection, and regression tasks.

Future research: I am interested in applying weak supervision and data generation to new tasks and domains, such as image and video editing; multimodal and 3D perception; and model safety.
