I am the lead epidemiologist and biostatistician for the Translational Research Center for TBI and Stress Disorders Center (TRACTS), a VA Rehabilitation Research and Development Traumatic Brain Injury National Network. I play a central role in the design and data management of TRACTS, a longitudinal, prospective cohort study that uses state-of-the-art information across the domains of biological function (including blood chemistry, genetics, epigenetics), clinical and psychosocial function, lifetime head trauma and blast exposure, deployment experience, neuropsychological function, and neural integrity. I have 17 years of experience as a researcher focused on biostatistics and epidemiologic methods, with a particular interest in addiction, suicide, and psychiatric epidemiology.
