Seven Major Research Areas in Notre Dame Physics

The Notre Dame physics PhD program offers research opportunities across seven major fields: astrophysics, atomic physics, biophysics, complex systems, condensed matter physics, high energy physics, and nuclear physics. This breadth allows students to find their niche within a supportive departmental community while benefiting from cross-disciplinary interactions that often lead to innovative research directions.

Each research area is led by internationally recognized faculty who maintain active research programs funded by federal agencies including the NSF, DOE, NIH, and DARPA. The department’s research portfolio spans from the most fundamental questions about the nature of matter and the universe to practical applications in medical physics, materials science, and network theory.

The diversity of research programs also means that doctoral students have opportunities to pivot between research areas during their early graduate career, exploring different topics before committing to a dissertation project. This flexibility is particularly valuable for students entering graduate school with broad interests who want to make an informed choice about their specialization.

Astrophysics Research at Notre Dame: From Dark Energy to Exoplanets

The astrophysics group at Notre Dame encompasses both theoretical and observational research programs that have produced landmark discoveries. Faculty members have co-discovered the acceleration of the universe’s expansion (dark energy), discovered the oldest known star in the galaxy (HE 1523-0901), and discovered the first Earth-like planet in a star’s habitable zone (Kepler-62e).

Notre Dame is a world leader in nuclear astrophysics, studying the elemental processes that occur inside stars, and an emerging leader in galactic archaeology — using the oldest known stars to probe conditions in the immediate aftermath of the Big Bang. The department has recently developed an experimental astrophysics laboratory for building cutting-edge telescope instruments operating at visible and near-infrared wavelengths.

The department’s partnership with the Large Binocular Telescope in Arizona — described as the largest and most advanced optical telescope in the world — provides Notre Dame researchers and graduate students with access to premier observational facilities. Additional resources include data from the Hubble Space Telescope and the Sloan Digital Sky Survey. Research published by NASA frequently builds on discoveries made by Notre Dame astrophysicists.

Nuclear Physics and the Nuclear Science Laboratory

The Nuclear Science Laboratory (NSL) at Notre Dame is the longest continuously operating nuclear accelerator laboratory at any U.S. university, a distinction that speaks to the program’s enduring commitment to experimental nuclear physics. The NSL houses three accelerators and a recently installed next-generation mass separator, providing state-of-the-art facilities for research in nuclear astrophysics, nuclear structure, and nuclear reactions with radioactive ion beams.

The nuclear physics program is ranked among the strongest in the nation, and Notre Dame is a founding member of the Joint Institute for Nuclear Astrophysics (JINA) — one of only 10 NSF-funded Physics Frontier Centers in the nation. JINA brings together researchers from multiple institutions to address fundamental questions about the origin of the elements and the nuclear processes that power stars.

A distinctive feature of the NSL is its emphasis on hands-on student participation in every aspect of experimental physics, from conception and design of experiments to construction of apparatus, accelerator operation, and data analysis. This comprehensive training produces doctoral graduates who are exceptionally well-prepared for careers in experimental physics at national laboratories, universities, and industry. The U.S. Department of Energy Office of Nuclear Physics recognizes Notre Dame’s NSL as a key contributor to the national nuclear physics research enterprise.

High Energy Physics: From the Higgs Boson to Neutrinos

The high energy physics group at Notre Dame maintains major roles in two of the most important particle physics experiments in the world: the CMS experiment at the CERN Large Hadron Collider (LHC) and the DUNE neutrino oscillation experiment at Fermilab and the Sanford Underground Research Facility. Notre Dame researchers played a key role in the historic 2012 discovery of the Higgs boson at the LHC.

Current experimental work focuses on measuring the coupling between the Higgs boson and the top quark, pursuing major detector upgrades for the CMS experiment, and preparing for the DUNE experiment, which aims to elucidate the neutrino mass hierarchy and CP-violating phases — fundamental questions that could explain why the universe is composed of matter rather than antimatter.

The theoretical high energy physics group complements this experimental program with research on physics beyond the Standard Model, signals of novel particles and phenomena at the LHC, flavor physics and CP violation, dark matter, and cosmology. Graduate students in high energy physics have the opportunity to spend time at CERN in Geneva, Switzerland, and at Fermilab near Chicago, gaining invaluable experience at world-leading research facilities.

Condensed Matter, Biophysics, and Complex Systems Research

The condensed matter physics program at Notre Dame spans both experimental and theoretical research, with particular strengths in nanoscale materials fabrication, spintronics, superconductivity, graphene and topological insulators, and scanning tunneling microscope (STM) spectroscopy. Experimental researchers collaborate actively with chemists, biologists, and engineers across the university.

The biophysics group takes an interdisciplinary approach to understanding biological systems at the molecular level, studying DNA, proteins, bacteria, viruses, and liposomes using techniques including laser transmission spectroscopy, photoelectron spectroscopy, and nuclear magnetic resonance (NMR). A collaboration with the Harper Cancer Research Institute enables research into new techniques for early cancer detection and treatment.

Perhaps most uniquely, modern network science was born at Notre Dame with the invention of scale-free (power-law) networks and the discovery of their ubiquity. The complex systems group continues this pioneering tradition, studying many-body behavior in physical and biological systems where disorder and strong interactions play important roles, with applications ranging from population genetics to swarm dynamics and social network analysis.

Funding and Financial Support for Notre Dame Physics PhDs
