Biological research is rapidly uncovering vast amounts of data. Mathematics can play an important role in helping to decipher the complexities of the biological world. I will discuss the applications of fluid dynamics, differential equations and statistics to human health research. In particular, I will describe my research using computational fluid dynamic models of airflow in the nasal passages to answer questions in toxicology and pharmaceutical development. I will also give examples of research into understanding complex metabolism problems and interpretation of the ever expanding amounts of DNA data. This talk assumes little mathematical background and will give some examples of jobs available for mathematicians in the pharmaceutical industry.
