Bryce Littlejohn

Bryce Littlejohn is an Associate Professor of Physics at Illinois Institute of Technology, affiliated with the Lewis College of Science and Letters. His research focuses on experimental nuclear and particle physics, with a particular emphasis on neutrino physics and radiation detector development.

Dr. Littlejohn's educational background includes a Ph.D. and M.S. from the University of Wisconsin-Madison and a B.S. from Principia College. His expertise spans experimental neutrino physics, nuclear reactor physics, and applied neutrino physics for nuclear non-proliferation.

His research interests center on neutrino detection and properties, with significant contributions to reactor neutrino experiments. Littlejohn is actively involved in major projects including the Fermilab Short-Baseline Neutrino Program, PROSPECT, and the Daya Bay Reactor Neutrino Experiment. His work has implications for fundamental particle physics as well as practical applications in nuclear non-proliferation monitoring.

Dr. Littlejohn's recent publications demonstrate a consistent focus on reactor neutrino measurements, detector development for liquid argon time projection chambers, and searches for physics beyond the Standard Model. His work spans both theoretical interpretation of neutrino data and practical detector engineering challenges.
