Koltun graduated in 1955 from Harvard University with a bachelor's degree[4] and in 1961 from Princeton University with a Ph.D. in physics with thesis New methods of spectroscopy applied to the nuclear 1-p shell.[5] He became in 1962 a member of the University of Rochester's physics faculty and retired there in 2004 as professor emeritus.[4]

He was a visiting staff member at Los Alamos Meson Physics Facility over a span of 18 years and served on the Facility's Program Advisory Committee. He was a visiting fellow at the Weizmann Institute of Science and at the Niels Bohr Institute. He was a visiting professor from 1976 to 1977 at Tel Aviv University and in 1985 at the Hebrew University of Jerusalem.[2]

A theoretical physicist, Koltun's research interests and activities were largely focused on the study of nuclear structure and reactions at intermediate and high energy, as well as with many-body theory. He was interested in understanding the dynamics of nuclei as many-body systems, and the role of subnucleon constituents in this problem, including mesons – particularly pions – and quarks. In addition to being a leader in the meson physics community, Koltun was known for what is called the "Koltun Sum Rule" for the scattering of electrons from nuclear targets.[1]

Koltun held an Alfred P. Sloan Research Fellowship from 1969 to 1971 and was elected a Fellow of the American Physical Society in 1972.

Upon his death he was survived by his widow, two children, and four grandchildren. The University of Rochester's flag (with the motto Meliora, located on the Eastman Quadrangle) was flown at half-staff in his memory.[4]

gollark: Due to those, yes.
gollark: ++apioform
gollark: Unfortunately, this is not possible.
gollark: So I thought "what if I made the random stuff API secretly running 28% of osmarks.net even more convoluted by integrating a trivial LDAP server to just return some data from a config file, and also connecting this with the HTTP frontend for nginx subrequest authentication?".
gollark: However, OpenLDAP was very annoying.
