Theoretical Nuclear and Particle Physics
My research lies at the boundaries of nuclear and particle physics, with some projects overlapping with astrophysics as well.
In order to expose the mechanisms that could help explain the vast preponderance of baryonic matter over antimatter in the cosmos, and possibly its dark matter, members of my research group and I are working towards new paths of identifying new sources of matter-antimatter (CP) symmetry violation as well as of baryon number nonconservation, also using astrophysical observables.
I am also interested in new ways by which terrestrial experiments can probe the nature of dark matter. This interest has spawned "data mining" projects to investigate the local structure and symmetries of the Milky Way and concomitant astrophysical constraints on its dark matter.
One long-standing interest has been the study of the discrete symmetries C, P, T -- and the manifestations of their violation -- in the structure and interactions of hadrons.
The interpretation of precision, low-energy measurements of hadronic processes to infer the existence of emergent, high-energy phenomena can require quantitative assessment of the Standard Model contributions. Thus I am also interested in improving our understanding of the non-perturbative dynamics of the strong interaction, particularly as it impacts the reliability of such predictions.

Postdoc Job Opening via N3AS
The Network for Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) is seeking applicants for three post-doctoral openings associated with the N3AS Physics Frontier Center. N3AS research focuses on theoretical issues in multi-messenger astrophysics, including studies of dark matter, dense matter, neutrino physics, and nucleosynthesis that impact gravitational waves and their interpretation, neutron stars and their mergers, and supernovae. N3AS interests also include fundamental symmetries and weak interactions. N3AS provides a unique multi-disciplinary environment for postdoctoral Fellows to address fundamental questions in astrophysics, cosmology, nuclear physics, and particle physics. All N3AS appointments are made through UC Berkeley. N3AS postdocs spend their first two years at one of the N3AS institutions. This year the available host institutions are Kentucky, Notre Dame, and Ohio University.
The N3AS Fellows selection committee includes all N3AS PIs. Interested candidates are requested to submit their applications before November 30, 2022 to ensure full consideration. Applications are being collected through Academic Jobs Online: https://academicjobsonline.org/ajo/jobs/22619. As early reviews of applications will begin November 16, any candidate who can apply by this earlier date is encouraged to do so. For further inquiries, please contact Susan Gardner (email@example.com), Daniel Phillips (firstname.lastname@example.org), or Rebecca Surman (email@example.com).
