Biostatistics involves the theory and application of statistical science to analyze public health problems and to further biomedical research. The faculty includes leaders in the development of statistical methods for clinical trials and observational studies, studies on the environment, and genomics/genetics. The department’s research in statistical methods and its interdisciplinary collaborations provide many opportunities for student participation.
To fulfill its mission to advance the health of all people around the world through research and training in environmental health, the department emphasizes the role of air, water, the built environment, and the workplace as critical determinants. Faculty members study the pathogenesis and prevention of environmentally produced illnesses and act as catalysts for scientifically based public health advances. Research approaches range from molecular studies to policy evaluation.
Epidemiology – the study of the frequency, distribution, and determinants of disease in humans – is a fundamental science of public health. Epidemiologists use many approaches, but the ultimate aim of epidemiologic research is the prevention or effective control of human disease.
Adaptation to alterations – in nutrients, lifestyle and dietary exposures, and environmental factors – is central to human health. The emphasis of the Department of Genetics and Complex Diseases is the elaborate interplay of biological processes with environmental factors as they apply to chronic, multigenic, and multifactorial diseases, with special attention to metabolism.
The Department of Global Health and Population (GHP) seeks to improve global health through education, research, and service from a population-based perspective. The 21st century has arrived with a complex set of demographic patterns, disease burdens, and health policies. These create challenges that affect all societies, rich and poor, developed and developing. The department's approach to these problems combines the analysis of population and health using quantitative and qualitative methods, the investigation of policies that affect health, and a concern with the politics and ethics of health and development.
The Department of Health Policy and Management is concerned with the mission of improving the health care delivery system and mitigating public health risks in the United States and abroad. It is dedicated to resolving major management and health policy problems through original research, advanced training, and dispute resolution.
The Department of Immunology and Infectious Diseases (IID) focuses on the biological, immunological, epidemiologic, and ecological aspects of viral, bacterial, protozoan, and helminthic diseases of animals and humans, and on the vectors that transmit some of these infectious agents.
The mission of the department is to improve human health through enhanced nutrition. It strives to accomplish this goal through research aimed at an increased understanding of how diet influences health, the dissemination of new knowledge about nutrition to health professionals and the public, the development of nutritional strategies, and the education of researchers and practitioners.
The mission of the department is to improve health throughout the human lifespan, including a special emphasis on children and adolescents. This mission is achieved through research to identify the social and behavioral determinants of health, the development and evaluation of interventions and policies leading to the improvement of population health, and the preparation of professionals and researchers who will fill leadership positions in advocacy and public service.
