Phiala E. Shanahan

Phiala Elisabeth Shanahan is an Australian theoretical physicist who lives and works in the United States. She is known for her work on the structure and interactions of hadrons and nuclei and her innovative use of machine learning techniques in lattice quantum field theory calculations.

Education Shanahan attended The Wilderness School in Medindie, a suburb of Adelaide, South Australia. While there, she received a 2007 Australian Student Prize. She received her BSc from the University of Adelaide in 2012 and her PhD from the same institution in 2015. In her doctoral thesis, "Strangeness and Charge Symmetry Violation in Nucleon Structure," Shanahan studied the role of elementary particles called strange quarks and charge symmetry breaking in the structure of protons and neutrons in atomic nuclei using lattice quantum chromodynamics and effective field theory techniques. During this time, she studied the role of force-carrying elementary particles called gluons in the structure of subatomic particles called hadrons. She also used lattice quantum chromodynamics techniques to examine the structures of atomic nuclei. In 2017, Forbes featured Shanahan in its "30 Under 30: Science" list for the impact of her work on the understanding of dark matter and physics beyond the Standard Model. From 2017 to 2018, she held a joint appointment as assistant professor at the College of William & Mary and senior staff scientist at the Thomas Jefferson National Accelerator Facility. Shanahan was also a Simons Emmy Noether Fellow at the Perimeter Institute for Theoretical Physics during the fall 2018 semester. Shanahan's current research includes seeking to understand how the structures and interactions of hadrons and atomic nuclei can be calculated from the fundamental principles of the Standard Model of physics, the role of gluons in the structures of hadrons and atomic nuclei, and how supercomputers and machine learning may be used to perform low-energy quantum chromodynamics calculations. Some of the predictions she is currently developing may be testable in the future using the Thomas Jefferson National Accelerator Facility's planned electron-ion collider.
