John Viator

John Viator entered the University of Washington in Seattle on a Naval ROTC scholarship in 1981 and received the B.S. in physics in 1985. After serving for four years on active duty as a surface warfare officer, he entered graduate school at the University of Oregon in Eugene, Oregon. He was recalled to active duty for Operation Desert Shield in 1990, where he served with the Military Sealift Command in the Persian Gulf Theater. He returned to the University of Oregon, where he earned the M.S. in mathematics in 1993.

He entered the Oregon Graduate Institute of Science and Technology in 1995, where he received the M.S. in applied physics in 1997. John finished his thesis on Characterization of photoacoustic sources in tissue using time domain measurements in 2001.

H John is currently a professor of biomedical engineering in the Duquesne University
