4 years of professional experience

Project manager in R&D

INSP - CNRS | 2015 - 2018 | Paris

Physicist at Sorbonne University

This professional experience is joined with my PhD. However this experience is much more than just sitting an exam. Indeed, undertaking a PhD in physics is to be a full time research scientist. The work undertaken during these three years were substantial as they pushed the boundaries of human knowledge in the field studied.

The subject of my PhD was Study and development of Localised Surface Plasmon Resonance (LSPR) based sensors using anisotropic spectroscopy. In other words, the work consisted in research a new kind of optical sensors for gas detection. The main gas we focused on was hydrogen. The project was supervised by Dr. Yves Borensztein For more detail on the work, you may download the thesis through the button below.

What did I accomplish ?

Ultra-sensitive gas sensor

Without going into the scientific details. The work focused on the study and development of an ultrasensitive gas sensor, mainly hydrogen.

We accomplished this using a differential UV-Vis spectrometer as well as an anisotropic LSPR nanoparticle sample. Everything in this research was developed in house. That is the optical apparatus, the nanoparticle samples as well as the software developed in LabView.

Skills acquired:
UV-Vis Spectroscopy

Scientific Conferences and publications

The work of a scientist is of course to do research. However research is useless if it stays in the lab. That's why scientific publication and conferences are essential. During this experience I attended many conferences and read a lot of scientific (peer reviewed) articles. I am also the author of 3 peer reviewed articles in reputable journals, and gave multiple presentations at international conferences. For a full list of publication, click here.

The PhD work was also written in the memoir, a 300 page thesis which can be download here. The optical sensor was also subject to a patent. This gave me valuable knowledge in intellectual properties and patent filling.

Oral presentation
Scientific writing


Scientific collaboration is vital. During this work, I was grateful to work with multiple research scientist to get further expertise on different ideas to improve the sensor. Indeed, I worked with Pr. Christian Serre and Dr. Antoine Tissot from the Paris Institute of Porous Materials (IMAP-ENS-ESPCI) in order to protect the sample. I also started a collaboration with Dr. Fabienne Testard from the Alternative Energies and Atomic Energy Commission (CEA).

The images below show the work undertaken with Pr. Serre et al. in order to put of metal organic framework (MOF) layer on the metallic nanostructure in order to protect the metal surface. What you can see are electron microscope images of the sample as the layer of MOF is grown.
