About me

My research interests include multi-modal fusion, image restoration, event-based algorithms, image/video generative models, and semantic segmentation.

I am interested in event cameras, a neuromorphic sensor that imitates the behavior of the human eye. Check out the introduction of the event camera and one of my project pages

I am also doing research on multi-modal fusion and  image/video generative models.

Before joining INSAIT, I led projects aimed at improving smartphone camera image processing pipelines in collaboration with several smartphone camera brands.
