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.

For a complete overview of my scientific output, here is my Google Scholar profile.
The goal is to distribute in all the lab a an optical signal that will be used as reference for all our home-made FTIR. For that I built a fiber network with constant monitoring of the reference laser.
With two Hilfassistant, a database of all the MIR mounted lasers has been created and filled.
Project in collaboration with D-ITET: implementation of a fast 0 crossing detection with Kalman filters on GPU for fast downsampling.
Build a 40 dB SNR with a contrast >95% interferometer for low signal spectroscopy with a 400 MHz resolution.
Stands for Music Of Week and Picture Of the Week because, why not?

Physicist, french, 33 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 and finding practical and elegant solutions.
Definitely a bike aficionado, I enjoy climbing - a lot -, swimming when possible, böötlen, and playing squash. Growing up in the mountains definitely left a mark, in winter you can find me on the slopes on all sort of skis (except telemark #weakknees). I do enjoy design, architecture, calligraphy, nerdy stuffs, food and food with good wine. Regarding other topic I enjoy discussing about languages, sociology, and trains. I can speak a bit of French, English, German and Spanish.
