Aviad
Dahan

I am a Generative AI researcher focused on audio-video personalization and generation, and a PhD candidate in the School of Electrical Engineering at Tel Aviv University, advised by Prof. Raja Giryes and Prof. Lior Wolf.

I work on generative AI for multimodal audio-video generation and editing, building models that can preserve identity, steer motion, and reshape visual stories.

My research spans personalized audiovisual generation, temporally coherent video models, and image editing. I am also interested in adapting foundation models to high-stakes visual domains, including medical image segmentation.
