Dr. Babu's Lab
Babu's research interests are primarily in the model-building and phenomenological aspects of physics beyond the Standard Model. He has been involved in studies of grand unified theories and nucleon decay. Babu is a key member of the neutrino theory community, having proposed several testable models of neutrino masses. His 1988 paper on two-loop generation of neutrino masses (the so-called Zee–Babu model) provides an alternative to high scale seesaw mechanism, and is well cited in the literature. He and Ed Kearns convened the Baryon Number Violation subgroup of the "Snowmass" 2013 Community Planning Study. He has helped organize the Center for Theoretical Underground Physics (CETUP) series of international conferences on neutrino physics in Lead, South Dakota.
