Reimagining nuclear materials for the future of medicine
Nuclear medicine has come a long way since Henri Becquerel first observed the penetrating energy of radioactive materials in 1896. Today, technetium-99m alone is used in more than 40 million diagnostic procedures every year—from cardiovascular imaging and bone scans to cancer detection—making it the undisputed workhorse of nuclear medicine. That single statistic tells you something important: An enormous portion of modern diagnostic medicine rests on a surprisingly narrow foundation, one built around a small number of aging research reactors that were never originally designed for continuous isotope production.
Nuclear and Emerging Technologies for Space (NETS-2022) Plenary SPeaker
Professor
The University of Michigan-Ann Arbor
John Foster has worked in the area of advanced space propulsion for 30 years dating back to his undergraduate days as a summer intern at NASA Glenn on gridded ion thrusters. His research includes in-space propulsion technologies ranging from gridded ion thrusters to MPD thrusters as well as gas and liquid core nuclear thermal rockets. He worked on advanced propulsion for nearly 10 years as an employee at NASA before moving to the University of Michigan. At NASA GRC, he served as the ion thruster (HIPEP) principle investigator for the JIMO NEP mission. He also worked on an interstellar precursor high power ion engine as NASA GRC as well. He continued this research at Michigan and extended research effort into space nuclear power and propulsion systems as well. In parallel he has developed as a space nuclear power and propulsion design course. He has also carried out research relevant to space in situ resource utilization including water recycling/purification and plastics waste recycling using plasmas.
