DMesh: A Differentiable Representation for General Meshes

Matheus Gadelha
I am currently a Research Scientist at Adobe Research. I received my PhD from University of Massachusetts - Amherst while being supervised by Prof. Rui Wang and Prof. Subhransu Maji. I am interested in Computer Graphics, Vision and their intersections with Machine Learning. My work is focused on models and representations of tridimensional data for both discriminative and generative models.
Lately, I have been particularly interested in mechanisms to incorporate 3D capabilities into large generative models so we can properly control them and robustly create/understand 3D data. I am also broadly interested in techniques (not necessarily ML-based) that allow us to better manipulate and author 3D content.
Latest on my research:
Internships for PhD students: If you are interested in related areas to the ones I've mentioned above (or anything related to my previous research), don't be shy and send me an e-mail with your CV and a short description of the problems you are interested in working on. We are always looking for talented interns to join us at Adobe Research.
Academic Collaborations: If you are a professor or a student interested in working with me, feel free to send me an e-mail -- I am more than happy to discuss interesting research problems we could work on together (or even just to chat about research).
