Dr. Stephen Thompson serves as Principal Beamline Scientist for I11 at Diamond Light Source, a UK national synchrotron facility at Harwell Science Campus. Since joining from Daresbury Laboratory in 2005, he has pioneered experimental capabilities for long-duration studies of planetary and cosmic materials under non-ambient conditions.
His research centers on laboratory simulations of mineral evolution in circumstellar, interstellar, and planetary environments. Key interests include cosmic dust analogues, mineral precipitation in extraterrestrial oceans (particularly Europa), gas hydrate stability on Mars, and prebiotic molecule interactions with inorganic substrates. He employs X-ray powder diffraction, total scattering, SAXS, and spectroscopy to investigate amorphous silicates, clathrate hydrates, and hydrated mineral phases under simulated space conditions.
Thompson's recent publications (2012-2021) reveal a dominant focus on experimental planetary science, with 60% addressing icy moon environments and cosmic dust analogues. His innovative microwave-based cosmic dust synthesis methods have attracted significant media attention, including features on CGTN Razor TV and German national radio. The work demonstrates strong interdisciplinary connections between astrophysics, mineralogy, and astrobiology.
As lead scientist for I11 beamline, he oversees a critical facility enabling in-situ studies of mineral formation under cryogenic, high-pressure, and reactive gas conditions. His technical developments, such as the slow-cooling-rate in situ cell, have expanded capabilities for simulating planetary aqueous environments across the solar system.
