Kyle Beyer

Kyle Beyer

Graduate Student, University of Michigan

Kyle is working on extending nuclear reaction and structure models away from beta stability and towards the neutron-rich fission fragment region by folding experimental fission observables into the corpus of data that these models are fit to.
