Research Interests
My current research interests focus on developing micro- and nano- systems using electrochemical discharges with particular interest on nano-particle fabrication with applications to fuel-cells and similar fields. I also work on novel micro-machining technologies for a variety of materials, with focus on glass. Using tools and techniques of applied Nanoscience, our group studies green energy converting systems with particular focus on engineering nano-structured electro-catalysts.
