Gregory Petsko
Gregory A. Petsko (born 1948) is an American biochemist and member of the National Academy of Sciences. He has an endowed professorship at Weill Cornell Medical College, is an adjunct professor at Cornell University, and is a professor emeritus at Brandeis University. As of 2014 Petsko's research interests are understanding the biochemical bases of neurological diseases like Alzheimer's, Parkinson's, and ALS, discovering drugs (especially by using structure-based drug design), that could therapeutically affect those biochemical targets, and seeing any resulting drug candidates tested in humans. He has made key contributions to the field of protein crystallography.
