Research

In the QOE group, my research focuses on mid-IR QCLs and more specifically on comb emitting devices.

A few keywords to define my different research axes:

Also related to the different axes but not primary research: spectroscopy, FTIR, fast data processing, experimental setup enhancement, automation, and automated tests.

Main Projects

Starting 1st of March 2024, I will be involved in the design, fabrication and measurement of low dissipation Surface Emitting QCL also called QCSEL. Stay tuned for more info!



Side Projects

Not strictly science related but brings something to the lab ;)

About Me

Climbing in SO

Physicist, french, 31 yo postdoc fellow at the Physics department of ETH in Prof. Faist group studying QCLs would define me at the moment in a professional way.

I am a graduate from the engineering school Grenoble-INP Phelma (France/Grenoble) where I specialized in semiconductor Physics and optoelectronics.

What drives me in research is the unknown and the challenges of solving problem.

Definitely a bike aficionado, I enjoy climbing two times a week, swimming when possible, böötlen, and playing squash.

I do enjoy design, architecture, calligraphy, nerdy stuffs, food and food with good wine.

Regarding other topic I enjoy discussing about languages, cultural differences, sociology, hockey and trains.

I can speak a bit of French, english, german and spanish.

CV available upon request.
