As a member of the Sr1 group I work on pushing the frontiers of accuracy and precision. We do so by combining the best ultrastable lasers in the world with our carefully controlled 1D strontium optical lattice clock. Doing so will not only let us demonstrate the next decade of accuracy, but also use our clock to probe nature, from gravitational shifts to drifts in fundamental constants. In my free time I'm usually wandering around somewhere remote and cold with my wife.

The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
