Lam Nguyen is a professor at the University of Paris-Est Créteil and a junior member of the Institut Universitaire de France. She leads the Spectroscopy & Atmospheres group at the Interuniversity Laboratory of Atmospheric Systems, which develops and operates very high-resolution spectroscopy instruments for studying molecules of interest in atmospheric chemistry, astrophysics, and biology.

 

She received her PhD in chemistry in 2012 (RWTH Aachen University, Germany) and specializes in molecular jet microwave spectroscopy, with a dual focus on instrumental development and spectral analysis. During the pandemic period (2019-2022), she designed and built the innovative PARIS (Passage And Resonance In Synergy) spectrometer, which combines the sensitivity of a resonant cavity with the speed of a chirp excitation spectrometer. PARIS marked an important milestone in instrumental development in microwave spectroscopy, achieving a resolution of 2 kHz in chirp excitation, previously only accessible with a resonant cavity, and achieving record sensitivity at the ppb level with this same cavity. Her expertise in modeling and spectral analysis focuses on molecules with large-amplitude motions, with quantum tunneling and nuclear quadrupole coupling effects. She combines experimental data and quantum chemistry calculations to characterize molecular structures and their internal dynamics. Her work has applications in physical chemistry, astrophysics, atmospheric sciences, and biology, particularly in understanding odor molecules and natural substances. She is leading an ERC (European Research Council) Starting Grant project to develop new instrumental and spectroscopic approaches around these themes.
