Ashley P. Golden, PhD

Adjunct Lecturer


Ashley P. Golden, PhD who began her employment with Oak Ridge Associated Universities June 2012, serves as a biostatistician. She is responsible for planning, directing, and performing methodological assessments and statistical analyses that support occupational exposure and worker health epidemiologists and other scientists in research areas that include occupational epidemiology, radiation exposure/dosimetry, medical surveillance, environmental assessments, and survey analyses. She has served as a statistical subject matter expert for numerous epidemiologic investigations and interdisciplinary research studies for government agencies, academic institutions, and private organizations. She has extensive experience in the execution and verification of parametric and non-parametric modeling, multivariate techniques, and categorical analyses using SAS, R, and other software packages. She was principally involved in the development and on-going delivery of five-day workshops in statistics for radiation/health physics professionals and has contributed to the statistical and epidemiologic body of literature with 10 publications and numerous peer-reviewed and invited presentations.
