My research focuses on applications of renormalization group (RG) and effective field theory (EFT) methods to the microscopic description of nuclei and nuclear matter. EFT and RG methods have long enjoyed a prominent role in condensed matter and high energy theory due to their power of simplification for strongly interacting multi-scale systems. More recently, these complementary techniques have become widespread in low-energy nuclear physics, enabling the prospect for calculations of nuclear structure and reactions with controllable theoretical errors and providing a more tangible link to the underlying quantum chromodynamics.

The use of EFT and RG techniques substantially simplifies many-body calculations by restricting the necessary degrees of freedom to the energy scales of interest. In addition to extending the reach of ab-inito calculations by eliminating unnecessary degrees of freedom, many problems become amenable to simple perturbative treatments. Since a mean-field description now becomes a reasonable starting point for nuclei and nuclear matter, it becomes possible to provide a microscopic foundation for extremely successful (but largely phenomenological) methods such as the nuclear shell model and nuclear density functional theory (DFT) that are used to describe properties of the medium-mass and heavy nuclei.

My research program presents a diverse range of research opportunities for potential PhD students, encompassing three different (but interrelated) components that offer a balance of analytical and numerical work: 1) in-medium effective inter-nucleon interactions, 2) ab-initio methods for finite nuclei and infinite nuclear matter, and 3) density functional theory for nuclei.


Topics that could form the basis PhD research in my group include: calculating the equation of state and response functions for nuclear matter from microscopic inter-nucleon interactions, constructing next-generation shell model Hamiltonians and effective operators via RG methods, and developing microscopically based density functional theory for nuclei.
