Purification and Characterization of Secondary Metabolites

Thomas Crowley studied biochemistry as an undergraduate at the University of Illinois Urbana-Champaign. He then pursued graduate studies in molecular biology in the Division of Biology at the California Institute of Technology. As a graduate student and later during postdoctoral studies he used biochemical and genetic methods to examine the regulation of gene expression and the intracellular localization of proteins during animal development. He has taught courses covering a wide range of chemical and biological topics such as general chemistry, biochemistry, microbiology, cell biology and developmental biology. These courses were taught at Montclair State University in New Jersey, Columbia University in New York City, the University of California San Diego and National University in La Jolla, California. He has authored articles derived from his research in a variety of journals and articles derived from his teaching in Biochemistry and Molecular Biology Education (BAMBED). He is currently an adjunct faculty member in the Department of Mathematics and Natural Sciences at National University and a member of the American Chemical Society.
