Dr. Rollison’s primary research focus is the molecular epidemiology of human polyomavirus and papillomavirus infections in relation to cancer. Specifically, she has investigated the presence of JC virus (JCV), BK virus (BKV), and/or simian virus 40 (SV40) in brain tumors and bladder cancer, and conducted seroepidemiological studies of JCV, BKV and SV40 in the context of brain tumors, non-Hodgkin lymphoma and colorectal cancer. In recent years, she has expanded her research to encompass emerging cutaneous infections as risk factors for the development of non-melanoma skin cancers, including Merkel cell polyomavirus (MCPyV) and multiple types of cutaneous human papillomaviruses (HPV) in genera alpha, beta, gamma, mu and nu. Through this work, she has demonstrated that individuals with squamous cell carcinomas of the skin exhibit higher levels of antibodies to MCPyV and cutaneous HPV compared to cancer-free controls, and that the tumor tissues themselves contain DNA corresponding to the same types of viruses. Dr. Rollison is currently participating in the International Agency for Research on Cancer Monographs Working Group on Polyomaviruses.
