Dr. Ranish’s formal training is in biochemistry and molecular biology. He did his undergraduate work in biochemistry at Cornell University, and earned his Ph.D. in molecular and cellular biology from the University of Washington. During his doctoral dissertation, Dr. Ranish studied the molecular mechanism of transcription initiation by RNA polymerase II in the laboratory of Dr. Steven Hahn at the Fred Hutchinson Cancer Research Center. Using the yeast Saccharomyces cerevisiae, he applied biochemical, molecular biology, and molecular genetics approaches to address this problem. Dr. Ranish’s studies culminated in the identification and cloning of the genes encoding the general transcription factor TFIIA, and the development of an immobilized promoter system for isolating and studying transcription complexes. He used this system to define intermediates in the formation of preinitiation complexes, and to define the reinitiation complex. For his postdoctoral training, Dr. Ranish worked with Dr. John Yates, III and Dr. Ruedi Aebersold in the Molecular Biotechnology department at the University of Washington where he developed his skills in mass spectrometry based-proteomic technologies. Dr. Ranish joined Dr. Aebersold when he left the University of Washington to found the ISB in 2000.
