FRIB-TA Supported Scientists
Current Theory Bridge Faculty
Prof. Sebastian König, North Carolina State University [firstname.lastname@example.org] start date: 1/2020
Dr. König's research has centered around exploring the powerful tool of effective field theories in low energy nuclear theory. In addition, he is developing new methods for nuclear structure for a wide range of masses, as well as developments that work toward the unification of structure and reactions. These are important in the interpretation of a wide range of phenomena that FRIB will cover.
Prof. Saori Pastore, Washington University [email@example.com] start date: 8/2018
Understanding the fundamental interactions in nature and their symmetries is at the heart of the research being developed by Dr. Pastore. She explores the effect of weak interactions in nuclei, using Quantum Monte Carlo techniques to determine nuclear structure, and in particular beta-decays and weak transition matrix elements. Her research connects strongly with the fundamental symmetries program planned for FRIB.

Prof. Maria Piarulli, Washington University [firstname.lastname@example.org] start date: 8/2018
The nuclear force is the essential building block for ab-initio theories of the nucleus. Dr. Piarulli has been working with collaborators on the formulation of the nuclear force (and associated currents) for use in quantum Monte Carlo (QMC) calculations of nuclear structure and reactions. Although she is mostly involved in ab-initio calculations for light nuclei, these can provide important benchmarks to test other computational methods applicable to heavy nuclei, where the treatment of nuclear interactions and currents is much less controlled. For this reason, Dr. Piarulli's work is relevant to a large fraction of FRIB's scientific programs.

Current Theory Fellows
Dr. Chloë Hebborn, hosted by LLNL [email@example.com] start date: 10/2020
Dr. Hebborn's research focuses on the study of exotic nuclear structures via reaction processes. She has been working on improvements to the description of inclusive and exclusive breakup reactions, which are used to probe nuclei away from stability. She is also interested in the development of microscopically-based interactions from ab initio calculations. Her work will support the theoretical analysis of experiments performed at FRIB.
Dr. Christian Drischler, hosted by MSU [firstname.lastname@example.org] start date: 10/2020
From atomic nuclei to neutron stars, the physics of neutron-rich matter covers an extreme range of densities. Dr. Drischler’s research focuses on applications of chiral effective field theory and many-body perturbation theory to derive microscopic constraints on the nuclear-matter equation of state and the structure of neutron stars. He has been developing Bayesian methods for quantifying effective field theory uncertainties, which enable statistically robust comparisons between nuclear theory, observational, and experimental constraints obtained in the FRIB era.
Dr. Kevin Fossez, hosted by ANL [email@example.com] start date: 3/2019
The research developed by Dr. Fossez explores the most exotic nuclei ever created. Fossez works on the unification of nuclear structure and reactions. This problem can be addressed either by extending ab-initio capabilities to continuum states, to increase predictive power in unknown regions of the nuclear chart, or by developing novel and more precise approaches at lower energy that take into account the existence of emergent phenomena in nuclei while still being properly connected with the more fundamental levels of description.

Past Theory Fellows
Dr. Diego Lonardoni
FRIB-TA Fellow at LANL, 2015-2020
The research carried out by Dr. Lonardoni contributes to building a predictive understanding of nuclear systems characterized by high neutron-to-proton imbalance, from neutron-rich nuclei to neutron stars, grounded in high-quality nuclear forces and ab-initio theory, including a complete assessment of all uncertainties associated with a nuclear many-body calculation. His results have impact on several FRIB experimental programs as well as other U.S. national laboratories.
Dr. Gregory Potel Aguilar, LLNL
FRIB-TA Fellow at MSU, 2016-2019
Dr. Potel’s research is in reaction theory and in particular reactions involving deuterons. Deuteron-induced transfer reactions are a popular tool in nuclear physics and recent applications of this probe have included exploring the structure of exotic isotopes and using them as an indirect tool for neutron capture processes. This is the context of Potel's work, which tightly connects with many FRIB experimental programs.
