Hall Bar
I am currently associate professor at ESPCI Paris - PSL in the Optical Conductivity Group. I work on the response of materials and devices in the THz frequency regime. If you are interested to work with us, feel free to contact me !

Postdoc at ENS Lyon

In 2020, I joined the Quantum Circuit Group as a postdoc at Ecole Normale Supérieure de Lyon, with Benjamin Huard and Audrey Bienfait. I was working on the Fluxonium Qubit, a superconducting qubit that has recently demonstrated promissing coherence times. I studied the effect of a strong measurement on the Fluxonium dynamics. A paper is in preparation.

Postdoc at The University of Sydney

From 2018 to 2020, I have been working at the University of Sydney in the QNL lab. The first year I worked on Dispersive Gate Sensing as a tool to probe low dimensional electronic systems such as Silicon spin qubits (UNSW) and in a quantum point contact (USYD). During the second year I developed a new method to define topological Josephson junctions in InAs 2D electron gas. More info here.

PhD at the ESPCI in Paris

In 2017, I obtained my PhD in the group of Jérôme Lesueur and Nicolas Bergeal (ESPCI), my work was focused on topological superconductivity at oxide interfaces. I characterized the superfluid stiffness as a function of doping and temperature at LaAlO3/SrTiO3 interface, and measured the first quantum point contact by field effect. More on this can be found here.
