About me

The limitations of computing and processing power are no small matter. Rather, they constitute a decisive question, which must be treated with the utmost respect.

- from "Computer meets Theoretical Physics"


Currently, I am a postdoctoral researcher in quantum computing at the IBM Research Lab in Zürich.

I obtained my Ph.D. in Physics at EPFL, in Lausanne, in the group of Prof. Giuseppe Carleo.

My research focuses on the development of quantum algorithms for the simulation of quantum systems.

I work to make the most of current quantum hardware, combining it with methods inspired by classical machine learning.
