Dr. Hondal received his Ph.D. in Chemistry from the Ohio State University in 1997. He then spent one year in the laboratory of Raymond Burk at Vanderbilt University studying the chemistry of selenomethionine and the structure of selenoprotein P. He continued his postdoctoral study under the direction of Ronald Raines at the University of Wisconsin-Madison as a NIH Postdoctoral Fellow. His work there focused on state of the art protein engineering techniques, including native chemical ligation and expressed protein ligation. His postdoctoral work at UW-Madison focused on methods for inserting non-natural amino acids into proteins as a means of addressing important structure-function questions in enzymology.
