Epidemiologists spend a significant part of their time performing research in laboratories. In researchers' efforts to find the root causes of diseases, some researchers specialize in the use of molecular epidemiology, so that they can delve further into cellular structures. Epidemiologists are a type of research scientist and their role is to look how disease spreads and why they spread in certain areas. What Are the Duties of an Epidemiologist.
