I am a Grainger Postdoctoral Fellow with the Enrico Fermi Institute at the University of Chicago, where I study the physics of neutrinos. My research includes both low-energy neutrino physics (SNO, SNO+, Theia) and short-baseline neutrino oscillations (SBND, MicroBooNE). From simulation-based design, to electronics instrumentation development, to physics analysis, I enjoy working on all aspects of experimental research.
The SNO+ Experiment has a broad program in neutrino physics, and is primarily focused on a search for neutrinoless double-beta decay in Tellurium, using a kiloton-scale liquid scintillator detector. SNO+ is a successor to SNO (The Sudbury Neutrino Observatory), the experiment which resolved the "solar neutrino problem," demonstrating that neutrinos have mass and change flavor en route to Earth.
The SNO+ Experiment is searching for neutrinoless double-beta decay (NLDBD) using a kilotonne-scale liquid scintillator detector located deep underground in Sudbury, Ontario, Canada. Additionally, SNO+ will search for nucleon decay (in an initial water-filled phase), low-energy solar neutrinos, reactor antineutrinos, geoneutrinos, supernova neutrinos, and exotic new physics scenarios. NLDBD is among the most exciting areas of nuclear and particle physics research. If this rare nuclear decay process is observed, it would imply that the neutrino is a Majorana fermion (i.e. its own antiparticle) and that lepton number is not conserved, as well as providing insight on the absolute mass of the neutrino.
Learn more about SNO+ at our homepage, our recent review article about the physics (doi, arxiv), or this cartoon-ey poster I made. You can also check out the UChicago SNO+ page or take a virtual tour of SNOLAB.
The Short-Baseline Neutrino Program at Fermilab is searching for sterile neutrinos using three liquid argon time projection chambers (SBND, MicroBooNE, and ICARUS T600) in a high-intensity neutrino beam. The SBN experiments will definitively address experimental hints of non-interacting 'sterile' neutrino species by searching for transitions of muon neutrinos into electron neutrinos over short distance scales, and also make measurements of neutrino cross sections with unprecedented precision.
There exist a number of experimental "hints" towards a fourth kind of neutrino, beyond the three known flavors. This 'sterile' neutrino would not interact with other matter, but be detectable by its effect on neutrino oscillations; for example, one might observe neutrinos seeming to disappear, as they convert into the non-interacting sterile state. The existence of a new neutrino would have major implications for our understanding of particle physics, and an experiment is needed to definitively test this hypothesis.
The Short-Baseline Neutrino Program at Fermilab uses a set of three neutrino detectors (liquid argon time projection chambers, LArTPCs) positioned along an intense beam of neutrinos. By comparing the kinds of neutrinos arriving at each detector, it is possible to confirm or rule out the sterile neutrino hints with very high confidence. Experience and new techniques developed at the SBN experiments will also benefit the upcoming DUNE experiment.
Particle physics depends on computing systems in many ways: high-performance clusters for simulations and analysis of very large experimental datasets, and robust networks for data acquisition and processing. From engineering the core on-site computing infrastructure for SNO+ to managing institutional grid computing resources, to developing data acquisition and analysis software, I am passionate about building computing solutions that enable science.
