Biostatistician Biostatisticians apply mathematics and statistics to the compilation, analysis, and reporting of health-related information. They also play a role in decision making and strategic planning of health programs. They might estimate what percentage of a certain population is likely to develop a disease, consider the likelihood of disease transmission, and look at data from clinical trials and studies to determine the best method of intervention. Biostatisticians also use their expertise in sampling and hypothesis testing to assist health investigators designing studies. They may specialize in demography or health data systems/vital statistics.
Epidemiologist Epidemiologists analyze the occurrence and distribution of diseases within a population, determine the possible vector or mode of disease transmission, and examine the efficiency of intervention programs. These public health scientists provide the data to help governments, health agencies, health care providers, and communities deal with epidemics and other health issues. Epidemiologists may specialize in infectious disease, chronic disease, environmental/occupational epidemiology, psycho/social epidemiology, health care evaluation, or human genetics.
Environmental Health Specialist An environmental health specialist (also referred to as environmental health inspector, environmental health officer, environmental health professional, environmental health sanitarian, environmental health scientist, and/or sanitarian) plans, develops, implements, and evaluates standards and systems to safeguard the health, safety, and welfare of the public from adverse environmental factors and to improve the quality of the physical environment as it affects health. They may collect, synthesize, study, report, and take action based on data derived from measurements or observations of air, food, soil, water, and other sources. They manage environmental health problems and promote public awareness of the need to prevent and eliminate environmental health hazards. They may also conduct inspections and take enforcement actions for environmental health laws and regulations. Currently, there is a great need for environmental health specialists in many states. While it is a well-paid profession, not many people are aware of this industry.
Health Educator Health educators plan, implement, and evaluate the effects of educational programs designed to support and modify health-related behaviors. They promote good health by educating the public about the causes of disease and the means of prevention on a community-wide level. Health educators also may provide counseling, plan programs, and organize community efforts. Public health workers within this area may specialize in the behavioral sciences, public health education, school health education, and communication theory/health media.
Public Health Nutritionist Public health nutritionists put science into action for the welfare of individuals and communities. They work on education programs for adults and children and teach practical ways for individuals to prevent disease or improve wellbeing through healthy eating. In communities, they create programs, work on projects, and form partnerships to improve health. Many work for the Supplemental Nutrition Program for Women, Infants, and Children (WIC). Some have a more clinical focus in, for example, pediatrics, diabetes, or obesity.
