I am Mehdi Langlois, a Research Technologist at NASA's Jet Propulsion Laboratory. I specialize in research involving optical ion clocks and atom interferometer inertial sensors. 

Prior to my current role, I was a Research Fellow at the University of Birmingham in the United Kingdom, where I led the conception and development of compact gravity gradiometers based on fibred lasers with a novel architecture. I was also a co-investigator for the development of a large area strontium interferometer within the AION Consortium, and I taught atom interferometry in group studies. 

During my PhD at SYRTE Laboratory at the Paris Observatory, I developed a gravity gradiometer using Bloch elevator and large momentum transfer beam-splitters. I also wrote a program to simulate atom chip magnetic fields and developed a process to fabricate atom chips. Additionally, I was a teaching fellow in two mathematics tutorial classes at the University of Paris-Sud. At the onset of my thesis, I worked on an active control of laser wavefronts in a cold atom gravimeter using a deformable mirror based on microelectromechanical systems.

Before my PhD, I worked as a research engineer at the Paris Observatory assembling and characterizing a compact microwave atomic clock using isotropic light cooling and microwave interrogation. With this experiment, I conducted interferometry and clock measurements in two campaigns of simulated microgravity flights.

I am a holder of a PhD in Quantum Physics from Pierre and Marie Curie University, a MSc in Fundamental Physics from University of Paris-Sud, and a BSc in Physics from University Paris-Sud.
