Marco Olivieri, the department's new Ramon y Cajal

Marco Olivieri joined the Universitat Politècnica de Catalunya (UPC) in January 2026 as a Ramón y Cajal Fellow. His research is centered on Mathematical Physics, with focus on the mathematical methods for many-body quantum systems and the interaction between microscopic quantum particles and radiation fields.

He earned his PhD in January 2021 from Sapienza University of Rome, where he also completed his Master’s and Bachelor’s degrees in Mathematics with maximum grades. Under the supervision of M. Correggi and M. Falconi, his doctoral research investigated the dynamical and stationary features of quantum fields interacting with particles and his work involved deriving effective models in the quasi-classical limit, utilizing techniques of semiclassical analysis and specific particle-field models such as the Nelson, Pauli-Fierz, and polaron models.

Following his doctoral studies, Marco held a postdoctoral position at the Karlsruhe Institute of Technology (Germany, 2020–2021), focusing on the proof of the Casimir-Polder effect. He then joined Aarhus University (Denmark, 2021–2023) as part of the "Mathematics of the Bose gas" project led by Professor Søren Fournais. This collaboration resulted in a publication establishing a second-order expansion for the energy of dilute Bose gases in the 2D thermodynamic regime.

In 2023, Marco obtained one of the highly competitive grants, the Marie Skłodowska-Curie Postdoctoral Fellowship, funding his research project "Universal Description of the Bose Gases" for 2 years at the University of Copenhagen. Marco worked with Prof. Søren Fournais and Jan Philip Solovej and their research group at the QMATH Centre.   

Throughout his career, he has remained an active member of the international Mathematical Physics community, including research visits to Universität Tübingen and the University of Rennes.
