Extensive experience as education counsellor; a wealth of knowledge in development and implementation of educational technology tools and applications in college classroom

Research: R & D experience with specialization in PVT properties of polymers and chalcogenides; Development of electrically conducting polymers composites for device applications such as sensor, EMI shielding etc.

Device fabrication: A   fascinating   fast-acting,   reproducible    electrical     switching   device of

Multiwalled carbon nanotube – polystyrene nanocomposites have been fabricated recently. The unique feature of these nanocomposites is the resistance which remains same even after triggering voltage. This effect has never been observed previously. Its application probably will seize business benefits and interesting objectives.
