Helen R. Quinn works as the Assistant to the Director for Education and Public Outreach and previously worked as a professor and chair of the PPA Faculty at the Stanford Linear Accelerator Center. Helen Quinn's work with Georgi and Weinberg on the unification of gauge coupling constants still plays a central role in attempts to find a unified theory of all interactions. The mechanism she proposed with Peccei to assure parity and time-reversal invariance in strong interactions has had far-reaching consequences for model building and axion searches. Her recent research has focused on deciphering the details of the tiny violations of these symmetries. She is a member of the BABAR collaboration at the Stanford Linear Accelerator Center that, together with the BELLE collaboration in Japan, provided the first evidence for such effects in B-mesons. She contributes to the Particle Data Group, which maintains an updated compilation of data in particle physics and cosmology, and has been active in outreach and education efforts. She has done important service for the national physics community, in particular as president of the American Physical Society. She was the 2000 winner of the Dirac Medal and is a member of the American Academy of Arts & Sciences (1998) and the National Academy of Sciences (2003). In 2016 she was awarded the AIP Karl Compton Medal. | |||
