David S. Armstrong serves as Chancellor Professor of Physics at the College of William & Mary within the School of Computing, Data Sciences, and Physics and Department of Physics. His experimental research primarily occurs at Jefferson Lab in Newport News, VA, focusing on fundamental particle interactions.
His academic credentials include:
- B.Sc. from McGill University (1981)
- M.Sc. from Queen's University (1984)
- Ph.D. from University of British Columbia (1988)
Armstrong's research centers on precision measurements in weak interaction physics through parity-violating electron scattering experiments. His work investigates proton weak charge, neutron skin thickness, and Standard Model validation using facilities like Jefferson Lab. Major projects include the MOLLER experiment, PREx (lead radius), and CREx (calcium radius) investigations, which probe nuclear structure and fundamental symmetries.
His publication trends reveal consistent focus on high-precision weak force measurements, with landmark papers in Nature (2018) and Physical Review Letters (2013) establishing new benchmarks for proton structure studies. These works demonstrate methodological advancements in electron scattering techniques and significant implications for beyond-Standard Model physics.
Scientific recognition includes:
- Monica Potkay Advisor of the Year (2022)
Armstrong actively mentors graduate researchers including current PhD candidates Kate Evans and Tasneem Raza, with historical supervision of numerous thesis students. His research receives substantial funding from the National Science Foundation (NSF), Canadian Foundation for Innovation (CFI), and Department of Energy, notably for the MOLLER experiment which achieved Critical Decision 3a approval.
He operates within large-scale international collaborations at Jefferson Lab, contributing to flagship projects including G0, PREx, CREx, and MOLLER that require multidisciplinary teams of physicists, engineers, and technicians operating advanced particle accelerator facilities.
