Hazel B. Nichols, PhD is an assistant professor in the epidemiology department.

Her work is based in large observational studies and data resources, including the Collaborative Breast Cancer Study, the Sister Study, the Cancer Research Network and the UNC Integrated Cancer Information and Surveillance System.

Dr. Nichols is a member of the Cancer Epidemiology Program at the Lineberger Comprehensive Cancer Center and a recipient of the North Carolina Translational & Clinical Sciences Institute (NC TraCS) Scholar Award.
