Brief Resume

Dr. Melissa Fazzari obtained her Ph.D. in Applied Mathematics and Statistics from Stony Brook University, and a B.A. in Mathematics from Boston University. Previously, she was an Assistant Professor in the Department of Preventive Medicine at Stony Brook University and in the Departments of Epidemiology and Genetics at Albert Einstein College of Medicine. She has been teaching basic to advanced Biostatistics for over 10 years, serving as co-director for the CRTP Biostatistics course at Einstein and teaching in the clinical trials course at Stony Brook. Dr. Fazzari has been a biostatistics consultant for many major medical institutions, including NYU, Mount Sinai, and Winthrop. She joined Winthrop in 2013 as the director of the Biostatistics Department, and focuses on overseeing the activities of the group as well as collaborating with Winthrop investigators. Dr. Fazzari also currently works with researchers at Mount Sinai developing prognostic models using methylation and gene expression data to predict treatment response and other patient outcomes in Mantle Cell Lymphoma.

Description of Research Interests/Activities

Dr. Fazzari's background includes 15 years' experience as a biostatistician for major research projects involving cancer, epigenomics, and the epidemiology of HPV progression in a large study of HIV-positive women. Dr. Fazzari's research interests are focused in clinical trial methodology as well as the analysis of high dimensional molecular data. Recently, she developed sample size formulae for three-level hierarchical clinical trials and has explored the robustness of these formulae to common real-world issues in clinical trials including missing data and treatment group imbalances. In the analysis of high-dimensional molecular data, Dr. Fazzari has expertise in the analysis, aggregation, and integration of data from genome- and epigenome-wide studies, developing a prioritization approach in methylation-based studies to incorporate biological priors with statistical testing in order to better identify novel candidate loci.
