Dr. Alexander has extensive experience in health research methodology, particularly in the conceptualization, design, analysis, and interpretation of epidemiologic studies. Dr. Alexander has published on a diverse range of topics and types of studies, including original epidemiologic research, qualitative reviews, and quantitative meta-analyses. He has conducted numerous “state of the art” reviews and weight-of-evidence assessments on complex medical and scientific issues.
Dr. Alexander has served as principal investigator on numerous projects related to occupational and environmental exposures and cancer outcomes. For example, he has examined a variety of chemical exposures, such as trichloroethylene, benzene, solvents, PCBs, arsenic, chromium, pesticides, asbestos, and dioxin and chronic disease and cancer outcomes. He has conducted community health studies and cluster investigations involving air, water, and soil exposures and disease endpoints. Dr. Alexander has extensive experience in cancer causation, and has conducted comprehensive reviews of lymphohematopoietic malignancies, such as non-Hodgkin lymphoma and multiple myeloma.
Dr. Alexander also has extensive experience in nutritional epidemiology, and has led several projects related to dietary factors and a variety of health outcomes. His work in this area includes conducting systematic qualitative and quantitative epidemiologic assessments of meat and fat consumption and cancer, examining the role of partially hydrolyzed whey protein infant formula in reducing the risk of atopic dermatitis, and assessing how fast food consumption is evaluated scientifically. He has presented his nutritional epidemiology research in a variety of professional venues, such as national conventions, scientific conferences, and governmental regulatory forums. Dr. Alexander is currently editing a textbook on Nutritional Epidemiology.
Dr. Alexander is a graduate of the University of Alabama at Birmingham (UAB) where he was awarded a National Cancer Institute Fellowship for Cancer Prevention and Control
. While at UAB, he worked closely with the Department of Pathology, where he designed and implemented epidemiologic studies pertaining to colorectal cancer survival. Dr. Alexander was the 2010 recipient of the UAB School of Public Health alumnus award for scientific excellence, based on recognition of his “significant scientific contributions through demonstrated commitment and exemplary leadership in empirical research, research methodology, or theory building or adaptation.” Prior to his graduate work at UAB, Dr. Alexander worked at the H. Lee Moffitt Cancer Center and Research Institute in Tampa, Florida where he worked on a clinical trial comparing two imaging modalities, digital vs. film mammography, for the Digital Medical Imaging Program in the Department of Radiology.
