Professional Interests:

Dr. Christensen's research is focused on combining advances in molecular biology, genomics and bioinformatics with the powerful techniques of modern epidemiology and statistics to characterize epigenetic states in human health and disease. His interests include understanding relationships between epigenetic states and exposures in the context of disease susceptibility, occurrence, and progression. By investigating complex interactions between the environment and somatic epigenetic alterations in target tissues, as well as epigenetic susceptibility traits in surrogate tissues, he hopes to develop their potential translational utility for diagnostic, prognostic, and/or treatment purposes.

Dr. Christensen received his B.S. from the University of Wisconsin Madison in Medical Microbiology & Immunology and French in 2002, and his Ph.D. from the Program in Biological Sciences in Public Health at Harvard University in 2008. He trained as a postdoctoral research associate in molecular epidemiology of cancer at Brown University in the Department of Pathology and Laboratory Medicine. Dr. Christensen joined the faculty at Dartmouth in 2011 as an Assistant Professor in the Departments of Community and Family Medicine in the Section of Biostatistics and Epidemiology, and Pharmacology and Toxicology.
