Bonjour, Hello!

I am a Ph.D. candidate at the McGill Graphics Lab (MGL), working under Derek Nowrouzezahrai. I am currently interning at NVIDIA AI as a Research Scientist in Deep Learning, where I have joined Sanja Fidler's group for the summer.

My main research interests lie at the intersection of physically-based rendering and machine learning. More precisely, I am interested in applying deep learning techniques to improve current rendering algorithms (e.g., denoising, path guiding, sampling). I also have an interest for differentiable rendering, 3D representation learning and Markov chain Monte Carlo (MCMC) methods for light transport simulations.

If you'd like to chat, feel free to send me an email.
