Keith B. MacAdam was born in Rochester, N.Y., attended Swarthmore College and earned a doctorate in Physics in 1971. After research at University of Stirling in Scotland, Yale University, and the University of Arizona, he came to UK as an Assistant Professor in 1977. He built a campus-based research program in experimental atomic-molecular-optical (AMO) physics with students and post-docs, supported by the National Science Foundation and the Research Corporation.

Dr. Stephen Parke Fermilab Neutrinos are the most numerous massive particles in the Universe. Their masses are very tiny, no larger than one millionth the mass of the electron. Are they like all the known massive fermions, being four component particles, or are they a new type of fermion never seen before, a two component fermion? Are there only only three neutrinos or are there more species of neutrinos? Of the three neutrinos we know of, we have determined part of the massing pattern but not the completely pattern.
