Supported the Marshall Space Flight Center ER23 Propulsion Systems Department Ares 1-X Roll Control System (RoCS) analyses efforts. Key contributions include analyzing the inner manifold explosion (zots) phenomenon, nitrogen tetroxide (NTO) flash freezing, and predicting RoCS thrust versus altitude. Zots and NTO flash freezing analyses involved investigating the physics of these phenomena, formulated and implemented an approach to assess the risk of these events on the Ares 1-X mission, and presenting res

Maintained fluid properties databases, responsibilities for which included using National Institute of Standards and Technology models to develop new Fortran-based fluid properties tables. Team lead of successful Ground Test Analysis Process Improvement effort – a process quality improvement effort. Member of Propulsion Systems Analysis (PSA) team which analyzes test and flight data of the Space Shuttle Main Engine (SSME) to characterize system and subsystem performance. In particular, analyze data and in

Independently performed in-depth analysis of innovative methods for suppression of enemy air defenses and presented white paper on results. Designed and developed specification requirements traceability database. Interfaced with team system engineers to develop various subsystem requirements for hardware and software upgrades to Air Combat Training Systems (ACTS). Responsibilities included defining system functional requirements, reviewing contractor documentation of requirements implementation, determinin
