Prior to joining the University of Idaho, Krishnan Raja held research faculty positions in the University of Utah, Salt Lake City, and the University of Nevada, Reno.

Before moving to the USA, he conducted research on environmental degradation of pressure boundary components of light water nuclear reactors in Tohoku University, Sendai, Japan for more than three years.

Raja has about four years of industrial research experience, where he developed welding consumables for surface modification of engineering components used in oil, cement, steel and construction industries for very high wear and corrosion resistance.
