Associate Professor
About
Professor Spitz’s group studies experimental particle and astroparticle physics. The group is involved in carefully measuring the properties of the neutrino, one of nature's fundamental particles, and in trying to understand the role of the "little neutral one" in the evolution of the universe. Specifically, the Spitz group seeks to address fundamental questions such as (1) Are matter neutrinos different than anti-matter neutrinos? (2) How many neutrinos are there? and (3) How does the neutrino acquire mass? While there are clear paths forward for answering these questions unambiguously, detecting and characterizing neutrinos is famously quite difficult. As such, the Spitz group is actively involved in neutrino detection technology development and implementation towards the eventual goal of fully understanding the neutrino and its past and present role in the universe
