What Does a Biostatistician Do?

Biostatisticians collect data from medical research and analyze it to draw conclusions or make predictions. They develop and execute research studies in collaboration with other statisticians and scientists and monitor clinical trials to ensure the integrity of the results. Biostatisticians must have exceptional written communications skills as they write research proposals and submit their findings to the scientific community. Some biostatisticians may also teach at universities while conducting their research, splitting time between the lab and the classroom. They are required to have an in-depth understanding of advanced statistical techniques, be familiar with analyzing clinical trials, and have excellent knowledge of epidemiology and statistics. The ability to plan, develop, and manage complex statistical computer databases is also important in this role.

Biostatisticians typically work in medical research, pharmaceuticals, public health, and clinical investigations. They should be familiar with specialized computer programs to analyze statistics and lab results. This role requires good collaboration skills as biostatisticians often interact with other scientists and researchers.
