Research
My current main research interest is image generative modeling, mainly deep learning methods for image modeling and imaging inverse problems.
Before that I was mainly focussed on the study of textures, from the theoretical analysis of stochastic image models to the development of new texture synthesis algorithms.
My work is at the intersection of image processing, applied probability, computer graphics, computer vision, and machine learning.
For more details, see my publications page.
