Dr. Ramona Gaza graduated with a BS in Physics from the Western University of Timisoara, Romania in 1997. She completed her graduate work and acquired her Ph.D. in Physics from Oklahoma State University. During the past five years, Dr Gaza’s research was focused on investigating Al2O3:C as a potential optically stimulated luminescence (OSL) radiation detector for space radiation dosimetry applications. Her investigations included several types of luminescence methods/materials (i.e., LiF:Mg,Ti, CaF2:Tm). Experiments included both ground-based measurements using accelerators such as the HIMAC Medical Accelerator in Chiba, Japan, and space radiation exposures during the STS-105 Shuttle Flight (2001) and as part of the BRADOS project to study space radiation exposure on the Russian segment of the International Space Station (2004).

Dr Gaza currently contributes to the Space Radiation Analysis Group (SRAG) at NASA Johnson Space Center with her research interests involving the investigation of several types of radiation detectors to be used for Low-Earth Orbit measurements. Duties include performing the routine radiation dosimetry for astronauts and implementing the OSL method as a viable radiation dosimetry technique at SRAG.
