Biography

Sangram Keshari Pradhan received his B.S and M.S degree in Physics with specialization of materials science from Berhampur University, India in the year of 2003 and 2005 respectively. In 2012, he got his Ph.D degree in Physics from Utkal University, India. Before joining in Center for Materials Research (CMR), Norfolk State University in the year 2013, he has worked one year at Institute of Materials Science, Bhubaneswar, India by getting Council of Scientific and Industrial Research, Govt. of India Research Associate Fellowship. His focused research is to explore alternatives materials instead of novel metals for plasmonics and metamaterial devices and their integration, fabrication of super-lattice/photonic crystals and epitaxial thin films for fabrication of various devices and its applications as well as synthesis of semiconductor nano-crystals/quantum dots for energy harvesting.

Research

  • Explored alternatives materials instead of novel metals for plasmonic and metamaterial devices and their integration:
