RESEARCH INTERESTS

Charles Jui is a member of the Cosmic Ray Physics Group and the High-Resolution Fly's Eye (HiRes) Experiment. Current activities include the measurement of energy spectrum of cosmic rays above 10¹⁸ eV from the monocular observation of the HiRes stage 0.5 ("Big H") detector and the measurement of cosmic ray composition near the "knee" (at about 10¹⁵ eV) with the Broad Lateral Non-imaging Cerenkov Array.

Dr. Jui is the production manager of the web-based interactive lessons as a part of the "Academic Science Projects Integrating Research and Education" (ASPIRE) in collaboration with the Utah State Office of Education. He also manages the production of interactive hands-on labs written in JAVA and distributed over the web/internet.
