# Roxanne P. Springer

### **Professor of Physics**

### Overview

Prof. Roxanne Springer works on weak interactions (the force responsible for nuclear beta decay) and quantum chromodynamics (QCD, the force that binds quarks into hadrons). The weak interactions are an excellent place to look for fundamental symmetry violations which may occur in nature, while the study of QCD is necessary for understanding protons, neutrons, and their partner particles. Dr. Springer uses effective theories involving these forces to study processes in both nuclear and particle physics.
