Antonio Pedro Ramos

About me:

I am currently postdoctoral fellow of excellence at the Instituto de Matemática Pura e Aplicada (IMPA) in Rio de Janeiro, Brazil. I obtained my PhD at Scuola Internazionale Superiore di Studi Avanzati (SISSA) in Trieste, Italy, where my advisor was Emanuel Carneiro (my thesis is available here). I am mostly interested in Fourier analysis and its interactions with number theory and approximation theory. My CV can be found here (updated June 2026).
