I am a theoretical physicist working at the intersection of quantum statistical mechanics, quantum information theory, and condensed matter physics. My research focuses on the emergence of collective quantum phenomena in non-equilibrium many-body systems, with an emphasis on quantum circuits, monitored dynamics, and resource theories of quantum computation.

I investigate how quantum information propagates, transforms, and gets encoded in complex quantum systems, particularly in the presence of measurements, noise, and competing unitary dynamics. This has led me to study measurement-induced phase transitions, error-resilient quantum encoding, and the dynamics of nonstabilizerness (magic) in quantum circuits. A central goal of my work is to understand how these fundamental properties shape the computational power, error correction capabilities, and complexity of quantum many-body systems.

To tackle these questions, I combine analytical approaches—including Weingarten calculus, random matrix theory, and mean-field methods—with computational tools, prominently replica tensor network and exact diagonalization. I like coding, in particular in Python, Fortran, C++, which I use to develop high-performance simulations and numerical frameworks for studying quantum dynamics.
