Research Investigators for the Men's Shift Worker Study

Scott Davis, Ph.D, Principal Investigator

Scott Davis, PhD, is Professor and Chairman of the Department of Epidemiology in the School of Public Health and Community Medicine at the University of Washington and a Full Member in the Program in Epidemiology of the Division of Public Health Sciences at Fred Hutchinson Cancer Research Center. Dr. Davis has directed major research activities investigating the effects of ionizing radiation on human health. One is a series of studies in the Russian Federation of the effects of radiation exposure from the Chernobyl Power Station. These studies have focused on the risk of thyroid cancer and leukemia among children in the Bryansk Oblast. The second is a long-term follow up study of thyroid disease in persons exposed to atmospheric releases of radiation from the Hanford Nuclear Site in eastern Washington State (the Hanford Thyroid Disease Study). He has conducted several epidemiologic studies of the possible health effects associated with exposure to power frequency magnetic fields, focusing on the risk of leukemia and breast cancer. This work has expanded to include investigations of the effects of exposure to light-at-night and circadian disruption on melatonin and reproductive hormones important in the etiology of breast and other hormone-related cancer. He has also maintained a long-standing interest in the etiology of leukemias and lymphomas, and has directed epidemiologic studies of Hodgkin's disease, non-Hodgkin's lymphoma, and multiple myeloma.

Janet Stanford, Ph.D

Dr. Stanford is a Member of the Fred Hutchinson Cancer Research Center and head of the Program in Prostate Cancer Research, and Research Professor in Epidemiology at the University of Washington. She is internationally known for her expertise in prostate cancer epidemiology and the Co-Principal Investigator of the Pacific Northwest Prostate Cancer SPORE. Dr. Stanford's main research interests focus on hormonal, environmental, lifestyle and genetic factors that may alter cancer risk, cancer progression, or disease outcomes such as cancer-specific mortality. The role of underlying genetic susceptibility based on rare, inherited and highly penetrant mutations as well as more common genetic variants of lower penetrance is also a major focus of her research. As a cancer epidemiologist, she has been involved in the development, implementation, and analyses of research studies of the etiology and progression of several different types of cancer, however, her primary focus is on prostate cancer.

Chu Chen, Ph.D., NRCC, DABCC

Chu Chen, PhD, is the Director of the Public Health Sciences Chen Laboratory and Associate Member at Fred Hutchinson Cancer Research Center and Affiliate Associate Professor in the Department of Epidemiology and the Department of Otolaryngology Head and Neck Surgery and Member of the graduate Faculty at the University of Washington. She is certified by the National Registry of Clinical Chemistry and the American Board of Clinical Chemistry. Dr. Chen's major research emphasis has been to understand the possible role of metabolic enzymes in the activation and detoxification of potential carcinogens in the environment, as well as steroid hormones and growth factors, in the etiology of cancer. Of particular interest is the contribution of genetic polymorphisms of these enzymes and receptor molecules for hormones and growth factors to susceptibility of cancer. She has also been a co-investigator on previous studies investigating the role of magnetic fields on urinary melatonin levels.

Michael Vitiello, Ph.D.

Dr. Michael V. Vitiello is Professor of Psychiatry and Behavioral Sciences, Adjunct Professor of Psychology and Adjunct Professor of Biobehavioral Nursing and Health Systems, University of Washington. Dr. Vitiello is the Senior Scientist of the Department of Psychiatry and Behavioral Sciences' Sleep Research Group. He has been an active researcher in the area of sleep and aging for over 20 years and is an author of over 250 scientific publications. Funded by the National Institute of Mental Health and the National Institute on Aging, his research efforts are focused on the neuroscience of aging, specifically; understanding the causes, consequences and treatments of age-related disturbances in sleep and circadian rhythms.

Marcia Killien, PhD, RN, FAAN

Dr. Killien is a Professor in the Department of Family and Child Nursing in the School of Nursing at the University of Washington. Dr. Killien's program of research focuses on the promotion of health of employed women and the interface between women's health and their work and family lives. This research has included identifying postpartum concerns of women, examining childbearing decisions of professional couples, delineating daily stressors and coping strategies of working women, and identifying the individual and environmental characteristics that differentiate women with good and poor health outcomes following return to work after childbirth, emphasizing strategies that promote health. She is currently investigating the relationship between stress and chronic headaches in adolescents, including testing the feasibility of school-based interventions as well as studying stress in registered nurses arising from interference between their family and employment demands.

Nancy Fugate Woods, PhD, RN, FAAN

Nancy Fugate Woods, PhD, RN, FAAN is Dean of the School of Nursing, and professor in the department of Family and Child Nursing, University of Washington. Since the mid-seventies, Dr. Woods has provided leadership in the development of women's health as a field of study in nursing science. Her early research focused on the relationship of women's social environments and health. Dr. Woods has led several large research projects focusing on women's perimenstrual symptom experiences. With collaborators at Duke University and the University of Washington, she conducted the first prevalence study of perimenstrual symptoms in U.S. women. Subsequent research focused on women's social environments, stress response, and ovarian hormones in the etiology of menstrual cycle symptoms. In collaboration with colleagues at the University of Washington, in 1989 Dr. Woods established the Center for Women's Health Research, focusing on women's health across the lifespan. Current research focuses on mid-life women, their health, and health seeking behavior patterns.
