Research
Activities:
non scholae sed vitae discimus*
* we learn not for school but for life
My research interests include Photonics, Plasmonics, and Numerical Treatment of Electromagnetic Problems. The general theme of my research is placed on devising novel devices for application in tomorrow's technology. However, being interested in multidisciplinary fields like Micortechnology, and Nanotechnology, I am always eager to conduct research forays.
