Matheus Gadelha

I am currently a Senior 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.

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.

Pro-bono Mentoring: If you are a student/early-career researcher/enthusiast seeking advice on research projects or general career directions, you can use this link to schedule a chat with me. I am particularly interested in chatting with folks from South/Latin America and helping in any way I can.

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).

Research Interns

I have been incredibly fortunate to have worked with amazing students. I keep a list of all the interns I have mentored/co-mentored below, and I am always happy to talk to students interested in research. Feel free to reach out!

Software

*I did not develop these by myself, but the list of collaborators is too big to include here. They are the result of a big team effort.
