Gelis is an professor in the Department of Chemistry and Biochemistry and is the Director of the Radiochemistry Program at 51³Ô¹ÏºÚÁÏ. As the program director, he manages the daily operations of the Radiochemistry Laboratory Complex (RLC). Gelis has a strong background and extensive experience in radiochemical separation techniques (solvent extraction, ion exchange) and actinide (Np, Pu, Am) solution chemistry. His expertise also includes radiochemical analytical methods (gamma-counting, LSC, alpha spectroscopy); electrochemistry, various spectroscopic techniques, kinetics and microfluidics.

His research interests lie in the area of actinide separations and speciation in aqueous and organic media; medical (e.g. Mo-99) isotope production and separation; and microfluidics relevant to the radio-analytical applications. Gelis has been the main contributor of the ALSEP process R&D. He has published more than 55 articles in peer reviewed journals in the field of radiochemistry.

Gelis is also an active Ph.D. advisor and is currently mentoring one post-doctoral researcher and seven graduate students.
