Research

Controllable generative models for adaptive visual content.

My research focuses on making pretrained multimodal generative models more controllable, reliable, and useful in real-world settings. I study diffusion-based image and video editing, compositional generation, and agentic refinement methods that diagnose and correct generation failures while preserving important visual details.
