Education
He received his bachelor"s degree in physics in 1979 from the Massachusetts Institute of Technology and his Doctor of Philosophy in physics at Harvard University in 1984. His Doctor of Philosophy work at Harvard introduced the theory of classical wave localization and, in particular, the localization of light in three-dimensional strongly scattering dielectrics.
Career
From 1984–1986 he was a Natural Sciences and Engineering Research Council of Canada postdoctoral fellow at the University of Pennsylvania, as well as a laboratory consultant to the Corporate Research Science Laboratories of Exxon Research and Engineering from 1985-1989. From 1986-1989 he was an assistant professor of physics at Princeton University. In 1987, while at Princeton he co-invented, along with Eli Yablonovitch, the concept of a new class of materials with a photonic band gap called photonic crystals.
This provided a fuller explanation of his original conception (1984) of the localization of light.
He was a laboratory consultant to Bell Communications Research (Red Bank, New Jersey) in 1989. In the fall of 1989 he joined the senior physics faculty at the University of Toronto.
He has been a Principal Investigator for Photonics Research Ontario and is a fellow of the Canadian Institute for Advanced Research. In 2011, John was selected as a Thomson-Reuters Citation Laureate.
Recently. In 2007, Doctor John was awarded the Curriculum Vitae Raman Chair Professorship of the Government of India.
Membership
Professor John is a Fellow of the American Physical Society, the Optical Society of America, the Royal Society of Canada, and a member of the Max Planck Society of Germany.
