Main research interests

My research is focused on quantum states in condensed matter physics. I design and manipulate electronic systems at very low temperature. I am an associate professor at ESPCI Paris - PSL, where I work on new THz spectroscopy techniques based on superconducting circuits for the study of fundamental excitations in correlated materials.
