01 · The overview

What is a Biostatistician?

Biostatisticians design and analyze clinical trials, interpret results, and develop statistical models. They collaborate with researchers to answer biological questions and contribute to advancements in medicine and public health.

Most days alternate between implementing analyses in code and shaping study design with clinicians: you write program code, clean data, produce tables and graphs, and perform longitudinal or logistic modeling. Time is also spent drafting analysis plans, preparing statistical datasets for committees or regulators, and reading current literature to select or justify methods for clinical research.
