Overview
Microarray technology, which provides a way to globally measure differential gene expression, promises to be extremely useful for the diagnosis, treatment, and prevention of complex disease as well as for the elucidation of biological mechanisms. These studies yield tens of thousands of simultaneous gene measurements from each biological sample. Issues in measurement and calibration of the microarrays need to be addressed appropriately in order to obtain valid datasets. To gain insight into genes and their function, patterns of expression and expression changes must then be discerned from high-dimensional data in which the number of observations is small relative to the number of variables.

The purpose of the one-day Shortcourse in Statistics for Microarray Data Analysis is to introduce statisticians and other researchers to statistical issues in the design and analysis of microarray studies of current interest to biologists and biomedical researchers. Experience with statistical methods and in data analysis is a pre-requisite, but no previous exposure to microarray data is assumed. The course will include the opportunity for participants to apply statistical methods to several datasets that will be provided.

Register early since space is limited to 90 participants (2 participants for each computer terminal).
