This is an exciting time for the emerging field of lipidomics. With the development and evolution of sophisticated mass spectrometers linked to highly efficient liquid chromatography systems, individual molecular species of lipids can now be isolated identified, and quantified, allowing us to begin to understand lipid metabolism and the treatment of lipid-based diseases (atherosclerosis, arthritis, cancer, diabetes, Alzheimer's disease, and other inflammatory diseases). Recent awareness that each category of lipid consists of thousands if not tens of thousands of individual molecular species requires sophisticated informatics to ensure consistent databasing and annotation of the numerous lipid molecular species and analysis of tremendous quantities of experimental data. The goal of this meeting is to bring together biological and biomedical scientists in a wide range of fields to share new findings and methods in the broader lipidomics field and to explore joint efforts to extend the use of these powerful new methods to new applications. Presentations will provide an excellent introduction for scientists new to these methods, and are sure to be of interest to lipidomics veterans who want to learn the latest techniques and research results.
