Sajeev John, O.C.
Sajeev John is leading a paradigm shift in the field of optical sciences. A professor of physics and Canada Research Chair at the University of Toronto, he has gained international renown by
co-inventing a class of materials known as photonic crystals, which allows light to be slowed down, contained and microscopically controlled. This breakthrough has already proven to have real-world applications in such areas as optical communications, health care, renewable energy and computing, and holds tremendous promise for launching an entirely new era of technology.
