I am a fifth year PhD student at IMPA, co-supervised by Marcelo Campos and Rob Morris. My research interests are Ramsey theory, probabilistic and additive combinatorics, and convex geometry. These interests are meant in a broad sense, and I am also open to learning about and working on other nice problems. See also my full academic CV.
