I am a PhD student in Jens Eisert's group at the Dahlem Center for Complex Quantum Systems, Freie Universität Berlin.
My research lies at the intersection of quantum information theory, learning theory, and complexity theory. I study how quantum computers extract useful information from unknown quantum systems—a key question in device characterization, quantum algorithms, cryptography, and verification. I’m also interested in classical simulation and quantum error correction.
