  • Castle, Philip, Ph.D.
    Dr. Castle’s interests are the science and translation of cancer prevention strategies; global health disparities research; epidemiology of human papillomaviruses (HPV) and cervical/anogenital cancer.
  • Chaturvedi, Anil K., Ph.D.
    Role of HPV in the etiology of head and neck cancers, natural history of head and neck cancer precursors, inflammation and cancer risk, role of inflammation in the etiology of lung cancer and other smoking-associated cancers.
  • Clarke, Megan A., Ph.D., M.H.S.
    Dr. Clarke conducts research combining molecular, clinical, and population-based approaches to address etiology, prevention, and early detection of anogenital, cervical, and endometrial cancers.


  • Gadalla, Shahinaz M., Ph.D., M.B.Bch.
    Dr. Gadalla’s research interests focus on identifying and characterizing individuals at high risk of developing cancer and discovering predictive and prognostic biomarkers that may guide therapeutic decisions for those patients.
  • Goldstein, Alisa M., Ph.D.
    Genetic epidemiology of cancer, integrating epidemiologic, clinical, and molecular approaches. Developing and evaluating methods to examine gene-environment interactions in complex diseases.


  • Khincha, Payal P., MBBS, MSHS
    Clinical evaluations and genetics epidemiology of individuals with Li-Fraumeni Syndrome. Diagnostic methods and clinical management of dyskeratosis congenita (DC), a cancer-prone inherited bone marrow failure syndrome and telomere biology disorder (TBD).
