Current Fellows in the Metabolic Epidemiology Branch

Meet the fellows in the Metabolic Epidemiology Branch (MEB) and learn about their work.

  • Zeinab Farhat, Ph.D., M.P.H.

    Dr. Farhat, postdoctoral fellow in MEB, investigates modifiable risk factors, particularly diet, for colorectal cancer using an integrated omics approach to better understand the impact of human and microbial metabolism on diet-cancer associations. Her mentor is Erikka Loftfield, Ph.D., M.P.H.

  • Joshua R. Freeman, Ph.D., M.P.H.

    Dr. Freeman, postdoctoral fellow in MEB, investigates the role of sleep timing and circadian disruption in health outcomes—specifically, the association between sleep and circadian exposures and cancer risk. In addition, he conducts methodologic studies to better understand the variability in key exposure metrics in this area of study, and to develop new modeling approaches for investigating behavioral exposures that may lead to circadian disruption and increased cancer risk. His mentor is Charles Matthews, Ph.D.

  • Jessica Gorzelitz, Ph.D., M.S.

    Dr. Gorzelitz, postdoctoral fellow in MEB, investigates the unique metabolic contributions of muscle and muscle-strengthening activity on cancer prevention, especially in gynecologic cancer, while also studying muscle-strengthening behavior and survivorship outcomes. Her mentor is Charles Matthews, Ph.D.

  • Andres J. Gutierrez Escobar, Ph.D.

    Dr. Gutierrez Escobar, postdoctoral fellow in MEB, works on the Helicobacter pylori Genome Project under the mentorship of M. Constanza Camargo, Ph.D., and Charles Rabkin, M.D., Infections and Immunoepidemiology Branch (IIB), as well as a gastric cancer genome-wide association study in Hispanics/Latinos. His mentors in MEB are Dr. Camargo and Christian Abnet, Ph.D., M.P.H.

  • Daniela S. Gutiérrez-Torres, Sc.D., M.S.

    Dr. Gutiérrez-Torres, postdoctoral fellow in MEB, is analyzing the impact of occasional smoking on cancer risk and mortality in the United States and worldwide. Her mentor is Neal D. Freedman, Ph.D., M.P.H.

  • Wayne Lawrence, Dr.P.H., M.P.H.

    Dr. Lawrence, postdoctoral fellow in MEB, investigates prostate cancer etiology, metabolomic profiling of cancer and other phenotypes, and racial/ethnic cancer disparities, under the mentorship of Neal Freedman, Ph.D., M.P.H., and Meredith Shiels, Ph.D., M.H.S.

  • Fangyu Li, M.S.

    Ms. Li, predoctoral fellow in MEB, is investigating the association between irritable bowel syndrome, inflammatory bowel diseases, and all cause and cause-specific mortality using epidemiological approaches, under the mentorship of Emily Vogtmann, Ph.D., M.P.H.

  • Jungeun Lim, Ph.D., M.P.H.

    Dr. Lim, postdoctoral fellow in MEB, investigates prostate cancer etiology and survival, including the role of micronutrients, vitamin supplementation, and circulating metabolites, as well as the genetic components of these exposures and associations. Her mentor is Demetrius Albanes, M.D.

  • Kathleen M. McClain, Ph.D., M.S.

    Dr. McClain, postdoctoral fellow in MEB, works on studies examining the components of energy balance, metabolomics, and cancer. Her mentor is Steven C. Moore, Ph.D., M.P.H.

  • John D. (Jack) Murphy, Ph.D., M.P.H.

    Dr. Murphy, postdoctoral fellow in MEB, investigates the etiology and prevention of precancerous gastric lesions with the goal of elucidating their risk factors and reducing the incidence of, and mortality from, stomach cancer. His mentor is Christian C. Abnet, Chief and senior investigator.

  • Omonefe Omofuma, Ph.D., M.S.

    Dr. Omofuma, postdoctoral fellow in MEB, investigates the descriptive epidemiology, etiology, and predictive biomarkers of esophageal adenocarcinoma and gastric cancer. Her mentor is M. Constanza Camargo, Ph.D.

  • Pedro F. Saint-Maurice, Ph.D.

    Dr. Saint-Maurice, research fellow in MEB, evaluates the impact of physical activity on health during midlife by examining activity duration patterns, intensity, and timing. He has also examined the relationship between daily step count and stepping intensity (steps/minute) with mortality in both healthy adults and adults with chronic conditions, including cancer. In addition, he examines how profiles of sleep and ambulatory movement throughout the day might be associated with cancer risk and mortality. His mentor is Charles Matthews, Ph.D.

  • Eleanor L. Watts, D.Phil., M.P.H.

    Dr. Watts, postdoctoral fellow in MEB, is investigating the role of physical activity in relation to cancer, under the mentorship of Steven C. Moore, Ph.D., M.P.H.

  • Zeni Wu, Ph.D., M.P.H.

    Dr. Wu, postdoctoral fellow in MEB, investigates associations between the human microbiome and cancer risk factors and cancer etiology, and is initiating new studies to understand the role of the microbiome from multiple sample types in breast cancer and head and neck cancer. Her mentors are Emily Vogtmann, Ph.D., M.P.H., Christian Abnet, Ph.D., M.P.H., and Rashmi Sinha, Ph.D.

  • Yukiko Yano, Ph.D., M.P.H.

    Dr. Yano, postdoctoral fellow in MEB, conducts methodologic and etiologic studies of the human oral microbiome as well as studies of risk factors for esophageal and gastric cancer. Her mentors are Christian Abnet, Ph.D., M.P.H., Rashmi Sinha, Ph.D., and Emily Vogtmann, Ph.D., M.P.H.

  • Ting Zhang, Ph.D., M.P.H.

    Dr. Zhang, postdoctoral fellow in MEB, investigates dietary factors, metabolomics, as well as genetic components of these exposures in the etiology of pancreatic cancer in cohort studies, under the mentorship of Rachael Stolzenberg-Solomon, Ph.D., M.P.H., R.D.

  • Semi Zouiouich, Ph.D.

    Dr. Zouiouich, postdoctoral fellow in MEB, conducts methodologic studies of the microbiome and etiologic studies of the association of the microbiome with different cancer types. His mentors are Rashmi Sinha, Ph.D., Emily Vogtmann, Ph.D., M.P.H., and Erikka Loftfield, Ph.D., M.P.H.
