Art Gelis

Art Gelis is a Professor in the Department of Chemistry and Biochemistry at the University of Nevada, Las Vegas (UNLV), serving as Director of the Radiochemistry Program and manager of the Radiochemistry Laboratory Complex (RLC). His expertise spans radiochemical separation techniques (solvent extraction, ion exchange), actinide solution chemistry, and analytical methods including gamma-counting, liquid scintillation counting, and alpha spectroscopy.

His research focuses on actinide separations and speciation in aqueous/organic media, medical isotope production (e.g., Mo-99 for Tc-99m generators), and microfluidics for radio-analytical applications. Gelis pioneered the ALSEP process for minor actinide/lanthanide separation and has published over 55 peer-reviewed articles in radiochemistry.

Recent publications (2021-2025) demonstrate concentration on X-ray spectroscopic characterization of actinide/lanthanide species, microfluidic separation systems, and solvent extraction chemistry for nuclear fuel cycle applications. Key themes include interfacial chemistry, third-phase formation, and medical isotope production optimization.
