A. Roberts works in theoretical and experimental particle physics, with a focus on testing fundamental symmetries of nature—especially CPT symmetry (which relates matter and antimatter) and Lorentz symmetry (which underpins Einstein's relativity). Much of this work examines how tiny violations of these symmetries might show up in neutral mesons (short-lived particles) and in high-energy astrophysical neutrinos. Some publications also touch on nuclear physics measurements and geological dating techniques.

Publication activity has been low and intermittent over the last decade, with a small cluster of papers around 2017 followed by occasional single papers in later years.
