Dr. Jacobsen's research is primarily in geo/cosmochemistry and nuclear forensics. He does isotopic and chemical in situ analyses of primordial solar nebular objects found in primitive meteorites to understand their chronological and compositional evolution within the proto-planetary Solar System disk. Dr. Jacobsen applies the same analytical techniques that he uses for his cosmochemistry research, to research isotopic and chemical signatures in nuclear materials.
