The mission of the Hixon Group is to broaden the participation of underrepresented groups in STEM and challenge misconceptions about nuclear energy by conducting research in environmental radiochemistry, inorganic actinide chemistry, and nuclear forensics. We attain this mission by training students across all "grade" levels (K-12, undergraduate, graduate, postdoctoral scholars) and through outreach to the local community.
