Dr. Thomas (Tommy) Fuerst joined the Fusion Safety Program at Idaho National Laboratory in 2019 as a research scientist. His research focus is hydrogen isotope interaction with fusion and fission materials and technology for tritium management in advanced reactors. His expertise is in measurement of hydrogen transport properties, membranes and membrane reactors for hydrogen separation, thin film deposition, and material characterization using techniques such as scanning auger microprobe, x-ray photoelectron spectroscopy, electron microscopy, and x-ray diffraction. Dr. Fuerst is a member of the executive committee for the American Nuclear Society Fusion Energy Division. When not researching tritium, he can be found in the mountains rock climbing, running, and skiing with his wife Meriel.
