Research Interests
Dr. Douglas Di Julio studied undergraduate physics at the University of Washington and received a M.S. in nuclear engineering from North Carolina State University in 2007. During this time, he gained in experience in neutron detection methods, Monte-Carlo simulations, and neutron diffraction measurements. He defended his PhD in experimental nuclear physics, titled “Probing single-particle and collective states in atomic nuclei with Coulomb excitation”, at Lund University in 2013. His work involved nuclear structure studies of neutron deficient radioactive Sn isotopes carried out at CERN and GSI.
Dr. Di Julio joined the Neutron Optics and Shielding Group at ESS in 2013. As a member of the group he has been working on Monte-Carlo simulations of shielding for neutron scattering instruments, performing radiation measurements at spallation neutron source facilities, and also implementing metaheuristic optimization methods for neutron instrument component design.
