Experience

  • Research Intern

    NASA Goddard Space Flight Center · Jun 2019 – Dec 2019

    Streamlined ground-truth validation and eliminated a proprietary IDL dependency in NASA's MODIS Dark Target aerosol-retrieval pipeline; two tools filed as NASA New Technology Reports.

  • Research Intern

    NASA Goddard Space Flight Center · Jun 2018 – Aug 2018

    Studied poleward aerosol transport using space-based lidar from the International Space Station.

  • Research Assistant

    UMBC — Department of Physics, ACROS Group · Aug 2017 – Jun 2020

    Atmospheric remote-sensing research on UMBC’s Taki supercomputer. NSF CyberTraining research in fall 2019 and coursework in spring 2020 were part of this longer appointment, with stipend support.

  • Teaching Assistant, Computational Physics

    UMBC — Department of Physics · Jan 2019 – May 2019

    Spring 2019 appointment for Introduction to Computational Physics (PHYS 220).

  • Teaching Assistant, Computational Physics

    UMBC — Department of Physics · Jan 2018 – May 2018

    Spring 2018 appointment for Introduction to Computational Physics (PHYS 220).

  • Computational physics teaching materials

    My 2018 computational-physics teaching solutions implement trapezoidal and Simpson integration, bisection and Newton root finding, interpolation and linear regression in Python.

Projects

  • Earth-Science Data Tooling — Packaged Scientific Python

    Project

    I developed scientific-data tools through NASA internships and UMBC research, including conversion to netCDF4 and parsing into pandas DataFrames. cosmic-crunch and noaa-gml-file-reader are published on PyPI; I also contributed to collaborative cloud-anomaly analysis.

  • Monte Carlo Photon Transport

    Project

    I built a Monte Carlo photon-transport model to explore how a cloud's optical thickness and absorption affect the light passing through it. The project began as my computational physics midterm at UMBC in spring 2017; the browser explorer here reconstructs that problem.
