Dan Melconian

Faculty: Professor



MIST M320 (main office)

CYCL 331 (aux. location)


Professor Melconian is interested in probing the fundamental symmetries of nature using the nucleus of the atom. Precision low-energy nuclear physics experiments are able to complement the searches going on at colliders and provide meaningful constraints on "new physics" –– physics not included in the Standard Model of particle physics.
