Diana is a Health Physicist for the Radiation Emergency Assistance Center and Training Site (REAC/TS) in Oak Ridge, Tennessee.  She serves as an emergency responder for the Nuclear Emergency Support Team (NEST) as an asset for the National Nuclear Security Association (NNSA) and the Department of Energy (DOE).  Prior to her work with REAC/TS, she worked under NNSA and DOE as a scientist for other NEST assets in the Aerial Measuring Systems, Nuclear Search Program and Consequence Management programs at the Remote Sensing Laboratory located on Joint Base Andrews Air Force Base. In addition to working under these national assets serving 24/7 on call, she conducted research for algorithm training and detector modeling, supported preventative radiological/nuclear detection for major public events, supported domestic radiological/nuclear response exercises, and performed domestic and international training under the Nuclear Incident Preparedness and Collaboration (NIPC) program, all of which falls under the Office of Counterterrorism and Counterproliferation. She also worked underground for the Stockpile Experimentation and Operations directorate at the Nevada National Security Site as a diagnostic scientist and supported the research and development of leading diagnostic technology for subcritical experiments.  She conducted dose analysis for participants during the nuclear testing time period at the Nuclear Testing Archives, and collaborated with other labs and sites in their dose reconstruction.  With a Bachelor of Science in Health Physics from the University of Nevada, Las Vegas, she is currently in pursuit of her Master of Science in Nuclear Engineering and continues to support NNSA/DOE with REAC/TS.
