**Meet the editor**

Dongfang Yang received his PhD degree in Physical Chemistry from the University of Guelph in 1995. He joined the National Research Council Canada in London, Ontario, in 2001 and is now a senior research officer. His current research interests include laser material processing; pulsed laser, sputtering, and e-beam deposition of thin films; new materials development for energy storage

devices; chemical and optical sensor development; and electrochemical studies of organic adsorption and self-assembly monolayer. He is currently serving as an editorial board member of eight scientific journals including the *Research & Reviews in Electrochemistry*, *Current Chemical Research,* and *Sensors & Transducers Journal*. He also holds an adjunct professorship at both Lakehead University and Western University in Ontario, Canada.
