I am a condensed matter theorist interested in the physics of strongly correlated electrons and ultra-cold atoms. My work is focused on trying to understand the unconventional phases and phase transitions of many-body quantum systems, using mostly analytical methods of quantum field theory. The subjects of my research are strongly correlated topological insulators, high-temperature superconductors (cuprates and iron-based), ultra-cold atoms in the unitarity regime, and frustrated quantum magnets.
