Dr. Ramona Gaza joined the Space Radiation Analysis Group at NASA Johnson Space Center in 2005 and currently serves as the Human Health and Performance (HH&P) Lead for the Non-Ionizing Radiation Team  and the Deputy Radiation System Manager for the Orion Multi-Purpose Crew Vehicle (MPCV).

Appointed Leidos Technical fellow since 2020, Dr. Gaza is supporting several NASA programs including the  International Space Station, the Orion MPCV, the Commercial Crew (CCP), the Gateway, the Habitation and Logistics Outpost (HALO), the Human Landing System, and the Commercial LEO Development. Her research and operations work focus on crew protection from space NIR sources such as lasers, natural and artificial incoherent light sources, and radiofrequency emitters; safety hazard analyses for ionizing and non-ionizing radiation risks; crew protection from environmental ionizing radiation including radiation measurements and data analysis using active instruments (e.g., direct-ion storage devices, Timepix technology, etc.) and OSL/TL radiation detectors; contributions to research studies on radiation  effects and mitigation for crew protection; space weather monitoring and real-time solar event contingency support to the NASA/JSC Flight Team.

Dr. Gaza currently serves as the Health Physics Society NIR Section President and is author/co-author for 100+ peer-reviewed publications and presentations and received a series of awards for her contributions to space exploration, most recent include: the Leidos Spot Award for sustained efforts in leading the JSC’s Non-Ionizing Radiation (NIR) crew protection across multiple programs such as the ISS, MPCV, Commercial Crew, Gateway and Human Landing System; the JSC Group Achievement Award for exemplary technical excellence in providing human system requirements and gap analysis to achieve a successful HALO PDR (2021); the Oklahoma State University Distinguished Alumni Award (2021); the NASA Group Achievement Award for SpaceX Demo-2 (2020); the NASA Award for Technical Excellence in Enabling the Successful Execution of the Orion MPCV Exploration Mission 2 Critical Design Review (2019); the NASA Group Achievement Award for significant contributions to the Bigelow Expandable Activity Module (BEAM) Project (2018); and the NASA CCP Team JSC Director's Innovation Team Award (2017).

She earned a B.Sc. in Physics from the West University of Timisoara, Romania, and a Ph.D. in Physics from Oklahoma State University, USA.
