Christina (Tina) Witcher has been active in numerous projects involving data from NHTSA’s national crash databases (such as FARS, CRSS, and NASS), naturalistic driving study datasets housed at VTTI, and experimental data. She is skilled in all facets of data management and analytics, including data collection, data preparation, data quality assurance, data standardization, data mining, event detection, and characteristics analysis. A senior project associate in the Division of Data & Analytics, Ms. Witcher also has extensive experience collaborating with researchers within and outside of the institute, including research planning, development of data specifications, and data diagnostics.
Before joining VTTI, Ms. Witcher worked for 14 years at Sandia National Laboratories in Albuquerque, NM, where she designed and implemented scenarios to assess algorithm-specific requirement compliance and identified vulnerabilities in satellite ground systems. This entailed maintaining, verifying, and validating large physics-based computer simulation models, performing root-cause analysis for anomalies, and leading major Red Team exercises for end-to-end system testing.
