Expertise

Dr. Ruggles received his B.S. in Chemistry from Ithaca College under Heinz Koch where he synthesized highly halogenated styrene analogs. He subsequently got his M.S. in Chemistry from Bucknell University under Thomas T. Shawe where he used a tandem ozonolysis reductive amination approach for the construction of novel quinocarcin analogues. Dr. Ruggles then received his Ph.D. in Organic Chemistry in 2003 from Michigan State University in the lab of Robert E. Maleczka Jr. where he elucidated chlorinative carbocation rearrangements of vinylic carbinols. His postdoctoral training began in the lab of Gregory K. Friestad in the Chemistry Department at the University of Vermont where he studied enantioselective radical additions to N-acylhydrazones mediated by chiral Lewis acids. He then continued his postdoctoral training at UVM in the Biochemistry Department under Robert J. Hondal as a NIH University Postdoctoral Fellow where he investigated the synthesis, conformations, and redox properties of disulfide containing eight-membered rings with application to thioredoxin reductases.
