I got my PhD in 2006 from the National University of La Plata. I was a Juan de la Cierva Fellow at the Autonomous University of Barcelona (2008-2011). In 2019 I got Full Professor position at the National University of La Plata. Since 2024, I am Associate Professor at the University of Barcelona. My research interests focus on Analysis and I have collaborated with mathematicians from Argentina, Austria, Brazil, France, Hungary, Greece, Spain, Sweden, and South Korea. I am editor of the Argentinian Mathematical Union Journal.

My research interests focus on:

- Spectral theory.
- Fourier analysis.
- Point processes.
- Geometric problems in operator theory.

In these lines of research, during the last years I have been working on crystalline measures and quasicrystals, the influence of the curvature in the boundedness of classical operators, ergodic theorems in metric spaces, and rigidity properties of certain point processes.
