Biostatistics is an essential tool for unmasking patterns and quantifying relationships in population health data, and for evaluating the effect of treatments, interventions and policies on human health. In this discipline, we use data to understand and improve health policy, to conduct biomedical research, and to properly analyze all forms of epidemiological and clinical studies. We also develop new techniques using the latest data science and machine learning tools for bioinformatics, to understand the huge volume of new data becoming available in this field.
