Sean McGuinness, Ph.D., joins ´óÏóÊÓÆµ as an assistant professor of physics, bringing a dynamic blend of research, teaching, and national service experience. Most recently a professor at Ivy Tech Community College, McGuinness also spent three years with the National Nuclear Security Agency (NNSA) after earning his Ph.D. and M.S. in Physics from the University of Notre Dame, where his research focused on medical applications of low-energy nuclear physics. His technical expertise spans nuclear and accelerator physics, alongside certifications in nuclear acquisitions, project management, and college teaching. Passionate about student engagement, McGuinness has a strong record of mentorship, public outreach, and leadership — whether teaching the physics of curveballs to kids or advocating for science funding on Capitol Hill.
