Roger Rowlett

Gordon & Dorothy Kline Professor of Chemistry, Emeritus

Department/Office Information



Research in my laboratory is focused on the elucidation of the structure and catalytic mechanism of enzymes. Resource guides in protein engineering and in protein X-ray crystallography document key methodologies in use by our laboratory and are suitable for faculty and/or undergraduate student training and consultation.
