Curriculum Vitae

Summary

Research Assistant Professor at the Southern University of Science and Technology, I am working on heat transport in novel thermoelectric materials. My role is to synthesize, characterize the morphology and measure the physical properties of low-dimensional and low-temperature thermoelectric materials.
Previously, I was a postdoctoral researcher at the University of Tokyo where I was working on phononic crystals to control the heat transport at nanoscale and also making Monte-Carlo simulations with a code of my own.
I made my Ph.D. at the university of Paris-Sud where I worked on thermal contact resistances at very low temperatures (below 2K).

In the frame of the JSPS Science Dialogue program, I had the opportunity to present my research and my life as a scientist to high school student (16 to 18 years old) for 90min.

Ma these en 180s 2014 (French 3-minutes thesis)

The aim is to present the thesis research topic in 3 minutes for a general audience.
Selected for the local Paris-Saclay final, I presented my thesis in front of a few hundred of peoples at the CNRS headquarter.
This very interesting experience was accompanied with professional in communication who taught how to communicate effectively about our scientific research to the general public.
