EVENT DESCRIPTION  
 
Event Type:  Seminar (This is an NIH Science event)
 
Title:  Self-Organizing Map Approach to Characterizing Complex Environmental Mixtures for Environmental Health Research
 
Description:  The complexity and dynamic nature of environmental pollution creates many challenges for health investigators seeking to illuminate health effects involving exposure to complex environmental mixtures. Identifying relevant mixtures, defining which are most important, and estimating health effects are some of the various challenges presented by this area of research. This talk will introduce the 'environmental mixtures problem' and then describe an approach that was found useful for research in this area -- the self-organizing map (SOM). This will entail a description of the SOM algorithm and its application to develop 'mixture' classification systems that can support research involving complex environmental mixtures. Application of the SOM will be illustrated using a variety of environmental data sets -- highlighting both benefits and limitations. Finally, this talk will demonstrate how to use SOM results epidemiologically in the context of an acute health effects study of air pollution. At the end of this talk viewers will have a better appreciation of the challenges presented by complex environmental data and become aware of an appealing tool to add into their 'mixtures' toolkit.
