  Graduate Research Assistant

  Worked on the MINERvA experiment as part of the University of Rochester neutrino group.Doctoral research focused on finding interaction probabilities of charged pion production off of heavy nuclei due to charged current neutrino interactions. Developed filteringand reconstruction techniques on large data sets.Developed techniques to select charged pions with good momentum reconstruction. Developed methods to better estimate invariant hadronic mass. Contributed in building a new C++ framework using object-oriented programming principles thatcentralized the measurement of systematic uncertainties, leading to more reliable data analytics forthe entire experimentStandardized the Python user interface that handles the deployment of large scale data andcomputation in order to support scientific big-data operationsImplemented scripting using a physics graphical framework built in Python to generate 10,000+ highquality scientific data visualizationsPart of a team that built a smaller test detector at Fermi National Accelerator Laboratory. Smaller detector was designed to provide energy calibrations for the main MINERvA detector.Conducted detector operations, data acquisition. Work provided extensive knowledge in Python, C++, ROOT, Latex, grid utilizationPresented at many collaboration plenary sessions. Presented MINERvA pion results at NUINT 2018Worked on the neutrino oscillation experiment T2K. Improved modelling of charged pion production in the NEUT simulation Show less
