Biostatistics is the branch of statistics which is characterized by its specific focus on biological, medical or epidemiological research questions. The biostatistics expertise within Swiss TPH covers all three of the aforementioned domains.  The Biostatistics unit of Swiss TPH has strong competences both in frequentist modeling (group of C. Schindler) and in Bayesian modeling (group of P. Vounatsou).  The latter group has a strong methodological research agenda (spatio-temporal disease modeling) whereas the former group is specialized in modeling short and long term effects of air pollution on health.  Moreover, the Biostatistics Unit offers statistical support within Swiss TPH and to customers from other faculties of the University of Basel. This support can be requested via the the Institute's home page.
