Krista Zanetti is a Program Officer in the Epidemiology and Genomics Research Program (EGRP), Division of Cancer Control and Population Sciences at the National Cancer Institute (NCI), National Institutes of Health (NIH). Dr. Zanetti earned her Ph.D. in Nutrition from Cornell University in 2003 and joined the Cancer Prevention Fellowship Program at the NCI. During the first year of her fellowship, she earned an M.P.H. at the Johns Hopkins Bloomberg School of Public Health. Dr. Zanetti then conducted primary research in the Laboratory of Human Carcinogenesis in the NCI’s Center for Cancer Research from 2004 to 2010. Since joining EGRP in 2010, Dr. Zanetti’s primary focus has been building infrastructure and capacity to support metabolomics in population-based studies. Most recently, she spearheaded collaborative efforts to establish the trans-NIH international Consortium of Metabolomics Studies (COMETS), which brings together 25 prospective cohorts and 3 well-established consortia from the U.S., Europe and South America (http://epi.grants.cancer.gov/comets/). COMETS allows investigators from across multiple disease phenotypes to: 1.) leverage existing resources and data; and 2.) work collectively to develop methods, tools and protocols for data harmonization and sharing, quality control and data standardization.
