Research Interests and Projects

My research interests mainly lie at the interface between Quantum Information Theory and Quantum Many-Body Systems. In general, I focus on applying tools from the mathematical fields of Analysis, Geometry and Probability to study problems arising in Quantum Information Theory. Moreover, a large part of my research deals with the Markovian description of open quantum systems and, in particular, with their study via Quantum (non-commutative) Functional Inequalities. 

More specifically, I am deeply interested in (but not restricted to) the following research topics:

  • Quantum Information Theory

  • Quantum Many-Body Systems

  • Quantum Dissipative Evolutions

  • Quantum Functional Inequalities

  • Entropic Inequalities
