Professor Gordon Gribble, Department of Chemistry, Dartmouth College, USAProfessor Gribble has been the co-editor of the annual book series Progress in Heterocyclic Chemistry for the past 10 years. His research programs involve several areas of organic chemistry, most of which involve synthesis: biologically active natural products, novel indole chemistry, anticancer triterpenoid synthesis, new synthetic methodology, and novel radical and cycloaddition chemistry of heterocycles.
