Experience

GNC Flight Software Engineer

2023 to Present at Aurora Engineering

I'm currently working on development, testing, and analysis for the Navigation and Mission Design branch at NASA. I work on the autoNGC and GEONS flight software packages in support of several lunar missions. autoNGC and GEONS provide onboard navigation to spacecraft. My work is generally composed of flight software and simulation development using C/C++/Python, and mission and navigation performance analysis using MATLAB. I am also the lead developer of MEDOS, which is a project that began as a Phase I SBIR in 2022 and has since been tested and flown on MMS to detect a radiation belt crossing using MMS's FEEPS instrument.

Instrument Ground Systems Engineer

2021 to 2023 at Aurora Engineering

In this role I supported ground system development and operations for NASA's MMS/FPI mission in the Geospace Physics Lab at NASA. I contributed to the design, calibration, and testing for a follow-on mission, HERMES/EEA, to launch onboard the lunar gateway. My work included the development of ground system applications to process and calibrate science and engineering data from FPI as well as lab work in ESD labs and clean rooms to test EEA. Once EEA was fully wrapped up and delivered, my role transitioned to support the autoNGC.
