Danielle J. Harvey, PhD, is an Associate Professor in the Division of Biostatistics, Department of Public Health Sciences, School of Medicine, at UC Davis. Her research primarily focuses on the statistical analysis of neuroimaging data. For the past fifteen years, she has worked in the area of Alzheimer’s disease, with particular emphasis on the use of neuroimaging to identify markers of disease progression. As such, she has expertise in the analysis of complex correlated data, whether the correlation is due to repeated measures from the same person (or animal) at a single time point (multiple brain regions or multiple electrodes, for example) or multiple measurements over time on the same person or animal (longitudinal studies). Dr. Harvey currently directs the Statistics Core for two studies of the effects of traumatic brain injury and post-traumatic stress disorder in cognitively normal Vietnam Veterans and Veterans with mild cognitive impairment using imaging and biomarkers in the Alzheimer’s Disease Neuroimaging Initiative (ADNI). She serves as a member of the Biostatistics Core for the UC Davis Alzheimer’s Disease Center and ADNI as well as the liaisons with the MRI and PET Cores for ADNI. She also serves as a member of the Biostatistics, Bioinformatics, and Research Design Core of the Intellectual and Developmental Disabilities Research Center at UC Davis. Through these shared resources, she has gained years of experience in collaborating with researchers with many different interests, assisting in grant development, study design, data analysis, and preparation of presentations and manuscripts. She will use her expertise to assist CounterACT investigators in study design, analysis, and interpretation of results.
