Physics professors Dan Bardayan and Manoel Couder were lecturers at the 2019 Exotic Beam Summer School, which took place on the campus of Oak Ridge National Laboratory from June 24-29, 2019. The aim of this annual school is to introduce students and young researchers to the various facets of the science of exotic nuclei including nuclear structure, nuclear astrophysics, fundamental interactions, and the application of nuclear science and technology. Bardayan lectured on "Nuclear Astrophysics Experiments", and Couder lectured on "Beam Optics". Both are researchers in the nuclear science laboratory in the Department of Physics.
