Biostatisticians apply statistical techniques to the analysis of biological data, including medical data. Some specific research interest of members if this group include design and analysis of data for clinical trials, epidemiology, flexible regression methods and analysis of count data, particularly time series of counts. Members of this group also have interests in the rapidly developing area of computational biology. Specific interests include the analysis of gene expression data sets, quantitative trait loci mapping, stochastic algorithms for genetical analyses and the analysis of flow cytometric data. Statisticians have a key role to play in the use of emerging technologies in biology. New technologies are allowing the collection of vast amounts of data for complicated biological systems. Making sense of these data, and beaing able to distinguish real patterns from noise and chance variation depends crucially on statistical expertise. Microarray studies of gene expression are one example of a new technology allowing collection of vast amounts of data and requiring statistical input for its interpretation
