Research

Atomic nuclei, the core of matter and the fuel of stars, are
self-bound collections of protons and neutrons (nucleons)
that interact through forces that have their origin in quantum
chromo-dynamics. Nuclei comprise 99.9% of all baryonic
matter in the Universe. The complex nature of the nuclear
forces among protons and neutrons yields a diverse and
unique variety of nuclear phenomena, which form the basis
for the experimental and theoretical studies. Developing a
comprehensive description of all nuclei, a long-standing goal
of nuclear physics, requires theoretical and experimental
investigations of rare atomic nuclei, i.e. systems with neutronto-
proton ratios larger and smaller than those naturally
occurring on earth. The main area of my professional activity
is the theoretical description of those exotic, short-lived
nuclei that inhabit remote regions of nuclear landscape. This
research invites a strong interaction between nuclear physics,
interdisciplinary, many-body-problem, high-performance
computing, and applied mathematics and statistics. Key
scientific themes that are being addressed by my research
are captured by overarching questions:

  • How did visible matter come into being and how does
    it evolve?
  • How does subatomic matter organize itself and what
    phenomena emerge?
  • Are the fundamental interactions that are basic to the
    structure of matter fully understood?
  • How can the knowledge and technological progress
    provided by nuclear physics best be used to benefit
    society?

Physics of FRIB

FRIB will be a world-leading laboratory for the study of nuclear
structure, reactions and astrophysics. Experiments with
intense beams of rare isotopes produced at FRIB will guide
us toward a comprehensive description of nuclei, elucidate
the origin of the elements in the cosmos, help provide an
understanding of matter in neutron stars, and establish the
scientific foundation for innovative applications of nuclear
science to society. FRIB will be essential for gaining access
to key regions of the nuclear chart, where the measured
nuclear properties will challenge established concepts, and
highlight shortcomings and needed modifications to current
theory. Conversely, nuclear theory will play a critical role in
providing the intellectual framework for the science at FRIB,
and will provide invaluable guidance to FRIB’s experimental
programs.

Biography

I was raised in  Warsaw, the capital and largest city of Poland. I first became interested in physics in high school in Warsaw (Poland), where I was fortunate to have an amazing physics teacher. She was a passionate educator who taught me the basic steps to solve physics problems. Later, when I attended the Warsaw University of Technology and Warsaw University, I had outstanding mentors who later became close friends and collaborators. They taught me how to be curious, how to find answers by connecting the dots, and how to enjoy research. My teachers made me who I am today.

At FRIB, I deal with various issues related to science. Before joining MSU in 2014, I served as the scientific director of the ORNL Holifield Radioactive Ion Beam Facility. and I was a Professor in Physics at the University of Tennessee and Warsaw University (Poland). I held several visiting positions, including professorships at Lund University (Sweden), University of Cologne (Germany), Kyoto University (Japan), University of Liverpool (England), University of the West of Scotland, Vanderbilt University, and Peking University (China).

How students can contribute as part of my research team

There is a nucleus in every atom. Atoms, in turn, make up matter—the stuff we interact with every day. But the atomic nucleus is still shrouded in mystery. As a nuclear theorist, I want to know what makes the atomic nucleus tick. My group's research provides a superb venue for the important mission to educate and train the next generation of scientists, who will play key roles not only in basic research itself, but also in numerous allied fields. The group is cosmopolitan:  it includes people from many different countries from five continents.  Students  are engaged in cutting-edge research that involves both analytic theory and high performance computing using modern computational techniques such as machine learning and the  statistical tools of uncertainty quantification.
