- B.S. Physics, University of Missouri-St. Louis, 1981
My research focuses on the intersections between particle physics, cosmology, and astrophysics. I have advised a large stable of PhD students who have gone on to becoming leaders at their research universities. The role of mentoring young faculty and fostering their research is very important to me. As such, I was the founding Director of CCAPP, designed specifically as a bucket-list destination for young scientists. I am a leading expert on Big Bang Nucleosynthesis and in particular limits on neutrino species using light element abundances. I also have done crucial work on the role neutrinos play in other cosmology and astrophysical environments (e.g., solar neutrinos and supernovae neutrinos). I expect to continue research in these and other directions over the next several years while at the same time working to make CCAPP the best place in the world for young scientists.
