Bailey Ethridge

Title: Mission Analyst

Missions/Projects: Earth Science Strategic Analysis

Study Topics/Expertise: Applied math/statistics, modeling and simulation, decision analysis, risk assessment

Bailey Ethridge first came to NASA Langley in 2020 and spent nearly three years supporting the Aeronautics Research Mission Directorate (ARMD) as a contractor with Analytical Mechanics Associates, Inc. (AMA). Bailey started as an analyst in ARMD’s Portfolio Analysis and Management Office (PAMO) and performed data validation, analysis, and visualization to inform strategic decision-making. She later joined the Aeronautics Systems Analysis Branch (ASAB) to support the System-Wide Safety (SWS) Project, assisting in the development and testing of risk assessment software as part of an in-flight safety management architecture.

In October 2022, Bailey moved across the hall and joined the Space Mission Analysis Branch (SMAB) as a civil servant where she now supports tool development for strategic analysis of international partnerships for the NASA Earth Science Division (ESD).
