Interview with Timothy James Symons, Senior Scientist at Lawrence Berkeley National Laboratory and recently retired as Associate Laboratory Director for Physical Sciences, for which he ran the Lab’s programs in high energy and nuclear physics. Symons explains how the Lab has responded to the pandemic and the wide range of physics research he is following at Berkeley and beyond. He recounts his childhood in England and his early interests in science and the opportunities that led to his undergraduate education at Oxford where a tutor focused his interests in nuclear physics. Symons explains his reasons for remaining at Oxford for graduate school and the relevance of the SU(3) shell model for his thesis. He describes his postdoctoral work at the UK Science Research Council, and the opportunities that initially led him to Berkeley to work with David Scott on low energy nuclear structure. Symons provides a history of the Bevatron and the many reasons that compelled him to take a staff position. He describes the challenges in replacing the Bevelac, and the import of the ISABELLE cancellation at Brookhaven on Berkeley’s decisions. He provides detail on the interplay between laboratory experiments and DOE policy decisions and he explains the significant administrative pull of his work for NSAC. Symons reviews broadly the state of U.S. nuclear physics in the 1990s and the value of the APS as a sounding board in shaping policies for the decade. He does the same for rare isotopes in the early 2000s and how the Lab became involved in DUSEL. Symons describes his world as Associate Lab Director and he discusses his interactions with the Lab Director which gave him a high-altitude appreciate for the broad range of research across the Lab. He explains the Lab’s contributions in energy research which stems from Steve Chu’s directorship. At the end of the interview, Symons reflects on the significant changes in the Lab’s scope and mission over his career, the overall trend that once-disparate research areas are now increasingly on a path of convergence, and he conveys optimism on the fundamental discoveries that are within reach for the near future of nuclear physics.
