Lipidomics, Proteomics and Genomics Research Group

The terms genomics, proteomics, and lipidomics refer to the systematic study of changes in gene expression, protein modification, and lipid mediators that occur in response to extracellular stimuli. Although most investigators in the Department of Biochemistry use these approaches in their research programs, the members of the Genomics/ Proteomics/ Lipidomics Group are at the forefront of the development and application of these technologies. These individuals, Drs. Spiegel, Sumitra Deb, Swati Deb, Beckman, Zehner, Kordula, Fang, Grogan, Roesser, Chen, and Milstien, are applying systems approaches to study important biological questions pertaining to cancer, heart disease, tissue repair and wound healing, and development.
