Bio

Daniel Phillips received his B.Sc. (Hons.) and Ph.D. degrees from the Flinders University of South Australia, graduating in 1995. From 1995-1998 he was a Post-doctoral Research Associate at the University of Maryland (College Park). In 1998 he took a position as a Research Assistant Professor at the University of Washington in Seattle, before moving to Athens to become an Assistant Professor in Ohio University’s Department of Physics and Astronomy in 2000. He has been a Professor at Ohio University since 2009. He has published over 100 papers in refereed journals, and his research is funded by the U.S. Department of Energy and the National Science Foundation. He has held Visiting Professorships at Chubu University in Japan, the University of Bonn and the Technical University of Darmstadt in Germany, and Chalmers University of Technology in Sweden. From 2014-6 he served as Chair of the Institute for Nuclear Theory Advisory Committee and he was Director of the Facility for Rare Isotope Beams Theory Alliance in 2022. He is the Past Chair of the APS Division of Nuclear Physics (DNP) Education Committee and a member of the DNP Executive Committee. He is a Fellow of the American Physical Society, and has been named an "Outstanding Referee" by The Physical Review.

Research Interests

Phillips develops theories of the atomic nucleus. His research seeks to understand the forces between the neutrons and protons inside the nucleus. At present he has three main interests:

Building models which describe the outcome of experiments in which beams of electrons and/or photons are directed on nuclei containing two or three neutrons and protons and the products of the collision are detected. The pattern of scattering reveals information on the arrangement of the nucleus' constituents.

Investigating nuclei which have a substantial neutron excess. Such nuclei tend to form an extended "halo" of neutrons around a central core of neutrons and protons: the neutrons spend much of their time a long way away from the other constituents of the nucleus. In consequence these halo nuclei have properties that are rather different compared to more "standard" nuclei. They share these peculiarities with other "large" quantum-mechanical systems (e.g. clusters of 4He atoms) where particles range far from each other.

Applications of Bayes' theorem to nuclear physics. Bayesian methods allow one to incorporate prior information in analyses of experimental data As such they are well-suited to models where there is a pre-existing information on the expected size of parameters. This is the case in the "Effective Field Theories" (EFTs) that Phillips uses to analyze the systems described under 1 & 2.

The experimental data Phillips works closely with is taken at various facilities around the world including the Thomas Jefferson National Accelerator Facility in Newport News, VA; the Triangle Universities Nuclear Laboratory in Durham, NC; the MAX-Lab facility in Lund, Sweden; the RIKEN facility in Japan; and the Facility for Rare Isotope Beams at Michigan State University.
