The Europa Clipper mission has numerous science payloads that are highly sensitive to contamination. To ensure the instruments are able to collect accurate data, it was critical to maintain the spacecraft within the allowable contamination budget.

I was responsible for developing the system that tracked all molecular contamination that was present on Europa Clipper. This included mapping all of the non-volatile residue (nvr) samples that were taken from the spacecraft. Tracking when there was an exceedance, and guiding where further sampling was needed.

This also included developing a model that simulated the molecular deposition on every instrument over the mission lifetime, based on measured outgassing from every flight component and material.
