Paul John Ellis (25 May 1941 – 20 February 2005) was a professor of physics at University of Minnesota for over 30 years. He is noted for his earlier work examining effective interactions inside nuclei, coupled channel approaches to nuclear reactions, and later work looking at dense nuclear matter inside neutron stars and developing a set of effective lagrangians that take into account scale and chiral symmetry.^[1]
