Ragnar Stroberg

Ragnar Stroberg is an Assistant Professor in the Department of Physics & Astronomy at the University of Notre Dame. His research focuses on ab initio methods for solving the quantum many-body problem in atomic nuclei, with applications to astrophysics and searches for physics beyond the Standard Model. He holds a PhD in Physics from Michigan State University (2014), an MS in Physics from the same institution (2011), and a BS in Nuclear Engineering from UC Berkeley (2009).

Key research areas include neutrinoless double-beta decay, dark matter detection via WIMP scattering, and theoretical modeling of nuclear matrix elements using renormalization group techniques. Collaborations include the Advancing Theory for Nuclear Double-Beta Decay (ATNDB), Nuclear Theory for New Physics (NTNP), and the Nuclear Computational Low-Energy Initiative (NUCLEI).

His GitHub repositories (imsrg, nutbar, etc.) highlight computational tools for nuclear structure calculations. Research outputs span high-impact journals, emphasizing precision calculations and uncertainty quantification in nuclear systems.
