What is an Epidemiologist? Epidemiology is the study of the distribution and causes of disease. It aims to solve or control health problems. Epidemiology integrates experiments, risk assessment, statistical analysis, surveys, and interviews to study disease patterns. Epidemiologists investigate patterns and causes of diseases and injuries that affect people. They try to reduce diseases and injuries through community education and policy. Environmental epidemiologists study diseases that are known or suspected to be caused by environmental factors.
