Alexie BOYER

Alexie BOYER is a CNRS Researcher at the Institut de Physique et Chimie des Matériaux de Strasbourg (IPCMS), affiliated with the University of Strasbourg, where he works in the Department of Ultrafast Optics and Nanophotonics (DON). His research focuses on ultrafast molecular dynamics in gas and liquid phases using extreme ultraviolet (XUV) light to probe electronic (attosecond scale) and vibrational (picosecond scale) processes through advanced photoelectron spectroscopy techniques.

Education

• PhD in Ultrafast Physics (2022) from Université Claude Bernard Lyon 1, thesis titled: ‘Attosecond and femtosecond dynamics induced by ultrafast XUV photoionisation in neutral molecules and complex biomolecular ions’
• Master’s degree in Atomic and Molecular Physics, Condensed Matter and Optics (2019) from Université Claude Bernard Lyon 1
• Bachelor’s degree in Physical Chemistry (2017) from Université de Lorraine

Research Focus

Dr. BOYER investigates photoionization-triggered dynamics across timescales, with expertise in:

• Attosecond interferometry for molecular charge distribution mapping
• Isotope effects in ultrafast internal conversion processes
• Conical intersections in organic molecules probed by XUV light
• Solvent and substituent effects on biomolecular relaxation
• Vibrational energy transfer in polycyclic aromatic hydrocarbons

Publication Trends

His recent articles consistently explore time-resolved molecular dynamics using XUV/X-ray techniques, with emphasis on isotope effects (deuterium), methyl substitution impacts on aromatic systems, conical intersections in heterocycles, and charge distribution metrology. Biomolecular applications have increased since 2022, particularly for nucleobases and peptides.

Awards and Recognition

• PhD thesis price Saint-Gobain 2022 (Société Française de Physique)
• JSPS Postdoctoral Fellowship (2022-2024) at Kyoto University

Laboratory Context

At IPCMS-DON, Dr. BOYER utilizes high-harmonic generation light sources and develops attosecond-resolved spectroscopic methods to study quantum dynamics in complex molecular systems, with ongoing work extending to biological environments.
