Michael D. Best

Professor, Director of Graduate Studies

Research

Research in the Best group entails bio-organic, synthetic organic, medicinal and supramolecular chemistry. This generally involves the design, synthesis and study of organic molecules for applications pertaining to biological systems. Our lab has a particular emphasis on lipid membranes, which are at the forefront of biomedical research since lipids control critical biological pathways relevant to disease, and are beneficial for applications such as drug delivery. One area of research in the group involves the development of smart liposomes for drug delivery through the design of responsive lipid structures. Additionally, we develop functionalized lipid probes that can be applied to elucidate the roles of lipids in biological processes. These projects utilize synthetic organic chemistry to access designer lipid targets, followed by biological and analytical chemistry studies to study and apply these compounds.


Biography

Dr. Best received his B.S. in chemistry from Boston College in 1997, where he worked with Prof. Lawrence T. Scott on the synthesis of fullerene derivatives. He received his Ph.D. in 2002 from the University of Texas at Austin, where he worked on the design and synthesis of fluorescent sensors for biomolecules in the lab of Prof. Eric V. Anslyn. Following this, he performed post-doctoral research with Prof. Chi-Huey Wong at The Scripps Research Institute. This focused on the application of carbohydrate microarrays for studying cell-surface interactions, as well as the development of heterocycle and nucleotide-derived inhibitors of sulfotransferase enzymes. In 2005, Dr. Best joined the faculty at Tennessee as an assistant professor of organic chemistry.
