Hi, I'm João Miguel Machado.
I’m a postdoctoral researcher at ENSAE/CREST, in the team of Anna Korba, supported by the ERC project Optinfinite.
I work on the calculus of variations, with an emphasis on optimal transport, geometric measure theory, and functional inequalities to understand the geometry and stability of optimization problems.
Research: understanding the landscape
Understanding an optimization problem starts with understanding its landscape. In Euclidean spaces, derivatives often reveal this geometry. In infinite-dimensional spaces, functional and geometric inequalities can play a similar role. I like to study the rigidity and quantitative stability encoded by these inequalities, and how they help us understand variational problems and their numerical schemes.
From Rio to Paris
Before joining ENSAE/CREST, I was a postdoctoral researcher in the Optimal Transportation team at the Lagrange Mathematical and Computational Research Center, led by G. Carlier, A. Figalli, Q. Mérigot, and F. Santambrogio.
I completed my PhD at Université Paris-Dauphine and the Mokaplan Inria team, supervised by Antonin Chambolle and Vincent Duval. Before that, I studied at EMAp FGV in Rio de Janeiro under the guidance of Maria Soledad Aronna.
Let’s talk mathematics
I am always happy to discuss mathematics, coffee, or just chat. Feel free to get in touch.
