  • Abnet, Christian C., Ph.D., M.P.H.
    Etiologic studies of esophageal and gastric cancers, with a focus on diet, environmental toxins, and the human microbiome.
  • Albanes, Demetrius, M.D.
    Nutritional and molecular determinants of prostate, lung, and other cancers. Focus on role of micronutrients, vitamin supplementation, and exposures related to energy balance and anthropometry.



  • Dawsey, Sanford M., M.D.
    Esophageal and gastric cancers: prevention and control, etiologic studies, especially in high-risk populations, and development of clinically useful techniques for early detection and treatment.


  • Loftfield, Erikka, Ph.D., M.P.H.
    Interplay between diet, metabolism, the microbiome and genetics and their effects on cancer risk. Leverages developing technologies to improve dietary assessment and gain insights into diet-cancer associations.


  • Matthews, Charles, Ph.D.
    Etiologic studies of the role of physical activity and energy balance/obesity in cancer prevention and control, as well as the development of better methods for the assessment of active and sedentary behaviors in population-based research.
  • McGlynn, Katherine A., Ph.D., M.P.H.
    Molecular epidemiology of primary liver cancer and testicular cancer.
  • Moore, Steven C., Ph.D., M.P.H.
    The role of physical activity and obesity in the development of cancer; diet biomarkers; metabolomics studies.


  • Sinha, Rashmi, Ph.D.
    Interdisciplinary studies of the role of diet in cancer etiology, especially the role of meat, poultry, and fish in relation to cancer risk. Study of non-nutritive constituents of diet, e.g., carcinogens formed during the cooking process and chemopreventive properties of coffee. Methods studies. Evaluating the associations of cancer risk factors with the human microbiome.
  • Stolzenberg-Solomon, Rachael, Ph.D., M.P.H., R.D.
    Prospective studies of dietary and lifestyle factors, as well as nutritional and molecular biomarkers in relation to primarily gastrointestinal cancers, particularly pancreatic cancer.


  • Vogtmann, Emily, Ph.D., M.P.H.
    Association between the human microbiome and cancer risk and evaluation of methods for collection, storage, and processing of samples and data for study of the human microbiome.
