Summary of Activities/Interests

Research in the Hixon group is built on understanding and quantifying the behavior of actinide elements in natural and engineered systems and falls within three broad themes: (i) environmental radiochemistry, (ii) the chemical and physical properties of nuclear materials, and (iii) synthesis and characterization of novel plutonium compounds.
