Research #
My research interests are generative modelling, information theory, and compression under computational and memory constraints. Data sources usually have some type of structure, such as graphs and sets. This means we can model and compress them better by taking this structure into account. Unfortunately, existing methods that do this are either sub-optimal (don’t achieve the Shannon bound) or computationally intractable. I’m interested in building computationally efficient compression algorithms that can be used with deep generative models on structured data, as well as their connections to bayesian methods.
Originally, I am from Florianópolis (Brazil) but I’ve lived in New Jersey, Orlando, Toronto (now), São Paulo, as well as other smaller cities in the south of Brazil.
Previously, I’ve interned at the Fundamental AI Research (FAIR) lab at Meta with Karen Ullrich in the summer of 2021.
I spent 2022 at Google AI with Lucas Theis and Johannes Ballé as a Student Researcher.
