My research emphasizes a fundamental theoretical understanding of the dynamics of plasmas in the Earth's magnetosphere, as well as in other planetary magnetospheres, the solar wind, and other astrophysical environments. I am particularly interested in the dynamics of the Earth's auroral regions. In these regions, strong currents flow along the magnetic field ("field-aligned currents") that are dissipated in the ionosphere and by accelerating the…

My current research focus is on theoretical particle physics, especially phenomenology at high energy colliders such as the Large Hadron Collider (LHC) and other future collider programs (ILC, CLIC, CEPC/SPPC, FCC-ee/hh, muon colliders, etc), spanning over interesting Standard Model (SM) phenomenology in particular the Higgs boson (exotic decays, Electroweak Phase Transition (EWPT) and Baryogenesis (EWBG), Effective Field Theory (EFT) ), Beyond…

Professor Kapusta does theoretical research on the properties of matter and radiation at high energy-density using relativistic quantum field theory. He is also doing research on the anti-de Sitter - conformal field theory correspondence arising from D-branes in string theory, and on the thermodynamics of nonlocal field theories arising from string theory.

The physical theories of primary interest include QCD, effective hadronic field theories,…

The primary goal of my research is the elucidation of the properties of disordered systems. Experimental investigations include studies of the electronic and optical properties of amorphous semiconductors, segregation phenomena in granular media , and fluctuation phenomena in neurological systems.

I'm a historian of science with a background in physics and philosophy. My research focuses on the genesis of relativity and quantum theory in the late-19th and early-20th century. I teach a survey of the history of science from the 18th through the 20th century, which meets two liberal education requirements (historical and international perspectives), a writing-intensive class aimed at physics majors on the history of 20th-century physics, honors…

My research involves building and analyzing experiments to probe the unknown physics beyond the Standard Model. Currently my group uses leptons, both muons and neutrinos, as that probe. Much of our recent effort has been building the detectors necessary to make the necessary measurements. Previously, my group built the massive NOvA neutrino detector that is still taking data and we are now building the electron tracker detector modules for Mu2e.

We are building instruments with which we observe the cosmic microwave background radiation (CMB). The CMB is a relic remnant from the big bang. Detailed characterization of the properties of the CMB have given and will continue to give a tremendous amount of information about the evolution of the universe. By 'evolution of the universe' we mean: throughout most of the age of the universe, from immediately after the bang until galaxies and clusters of…
