Calvin Howell



B.S. (physics) Davidson College in 1978;

Ph.D. Duke University (1984)

Full Professor of Physics Duke University


Calvin Howell received his Ph.D. from Duke University in 1984 with a research specialty in experimental nuclear physics.  After working for a year as a Post Doctorial Fellow at the Triangle Universities Nuclear Laboratory (TUNL), he joined the physics faculty at Duke University in 1985 as an Assistant Professor.  He is currently a Professor of physics at Duke University and the Deputy Director of TUNL.  He also has an Adjunct Professor appointment in the department of physics at North Carolina Central University.  The main trusts of his research program are in the areas of reaction dynamics in few-nucleon systems and the study of subnucleon degrees of freedom. He has held Visiting Scientist positions at Los Alamos National Laboratory, the Stanford Linear Accelerator Center, and Jefferson Laboratory.  Professor Howell demonstrates his commitment to the field of nuclear physics and to the academy through service.  He has served on the DOE/NSF Nuclear Science Advisory Committee, on the Executive Committee of the Southeastern Section of the American Physical Society, on several NSF grant review panels, and has contributed to the writing of two long-range plans for nuclear science in the U.S.  In 1998 he served the community as a Nuclear Physics Program Director at the National Science Foundation.  His desire to give back to his community is realized through his participation in activities that provide academic opportunities for minority students. He has served as a Faculty Coordinator for the Carolina Ohio Science Education Network, as the Faculty Coordinator for the Mellon Minority Undergraduate Fellowship Program at Duke University and is currently serving as the Academic Coordinator for the Minority Medical Education Program at the Duke University Medical Center. 


Calvin R. Howell has coauthored more that 70 articles in nuclear physics journals. He is involved in studies of the nucleon-nucleon strong force, especially the (weak) p-wave component at low energies, using polarized neutron scattering from proton and deuteron targets. The latter case also tests the latest 3-body calculations and is being used to search for 3-body forces. Precision measurements of scattering lengths are being used to look for violations of charge- independence in the strong force, a phenomenon which is related to up-down quark mass differences. Dr. Howell is also preparing to perform measurements of the electric and magnetic form factors of the neutron using the facilities at CEBAF. These observables will test our present quark models of the nucleon.
