**Research**

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.

**Biography**

I was born and raised in Cincinnati, Ohio, the 4^{th} (and only boy) of 5 kids. For the first 16 years of my life, I aspired to be a major league baseball player, a guitar player in a rock and roll band, or a historian. Physics wasn’t even a blip on my radar. This was primarily due to a miserable experience in my 7^{th} grade AP math class that completely destroyed my enthusiasm for math and science. It wasn’t until my junior year in high school that my interest was re-kindled by a particularly talented and quirky physics teacher named Mrs. Clemens. From that point on, I knew I wanted to pursue a career in the physical sciences. As an undergraduate at the University of Cincinnati, I majored in Nuclear Engineering. While I enjoyed the engineering curriculum, I quickly realized that my favorite classes by far were the “pure” physics courses. Once I took Quantum Mechanics in my third year, my mind was made up—I wanted to be a theoretical physicist.

**How students can contribute as part of my research team**

My research program presents a diverse range of research opportunities for potential PhD students, encompassing three different (but interrelated) topics: 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. The nature of these topics requires a mixture of theoretical and computational developments, which gives students flexibility to tailor their PhD research to match their interests.
