Timeline

publication

Two-dimensional gas chromatography time-of-flight mass spectrometry (GCxGC-ToF-MS) data analysis for identifying unknown persistent organic pollutants in milk samples

MS thesis. Analyzing chemical compounds in a large GCxGC-ToF-MS data repository.

software

mag-noise/crm — Constellation Ready Magnetometers processing code

Python processing with MATLAB CDF generation. A versioned, archived, citable software artifact.

dataset

Data for Enabling In-Situ Magnetic Interference Mitigation Algorithm Validation via a Laboratory-Generated Dataset

Separately captured trends, physical reaction-wheel proxies and pseudo-geophysical signals from four synchronised vector magnetometers. Known constituents, so an algorithm can be validated rather than assumed.

course

Convolution — instructional design module

An instructional module on convolution for undergraduate signal processing students.

project

Other Missions

Testing her approach on Parker Solar Probe, GOES and other missions, toward interference mitigation that works on any spacecraft.

project

E-POP / Swarm-Echo

The satellite behind most of her algorithm development and dissertation-proposal data, where reaction-wheel interference can be tracked in the time-frequency domain.

project

TRACERS

Graduate team member on the TRACERS mission led by Dr. David Miles, taking part in magnetic screening of the two satellites’ magnetometers.

note

HESTO Conference presentation

A 15-minute presentation on mitigating magnetic noise from spacecraft by tracking the time-frequency signature of reaction wheels.

note

Iowa students help develop NASA satellites

Graduate College feature on students helping develop NASA satellites, in which she discusses her work on TRACERS.

Three Minute Thesis — Honorable Mention

Judge-selected Honorable Mention in the College of Engineering Three Minute Thesis competition, after rebuilding her slides from the graduate-round feedback.

talk

Mitigation of reaction wheel interference and other noise sources in spacecraft using remote sensing and laboratory-generated data

First-author poster. Testing a spectral-domain mitigation algorithm on e-POP/Swarm-Echo data and on a laboratory dataset where both the noise and the geophysical signal are known.

talk

Mitigating Magnetic Interference in Space Science Missions: A Case Study of Feature Separation Techniques

First author. A case study in separating reaction-wheel interference using two vector magnetometers along a boom, with results from e-POP/Swarm-Echo.
