Ram Chandra Subedi (RC) is a Ph.D. student at Photonics Lab under the supervision of Professor Boon Ooi at King Abdullah University of Science and Technology (KAUST). He received his B.Sc. and M.Sc. in Physics from Tribhuvan University, Nepal in 2009 and 2011 respectively. In addition, he received his M.S. in the Experimental Condensed Matter Physics University of Georgia, Athens (UGA in 2016). During his stay at UGA, he worked as a Teaching/Research Assistant. His research at UGA was primarily focused on polymer/ small molecule-based Organic Light-Emitting Diodes (OLEDs) and Organic Spin Valves (OSVs).  Also, he has been teaching high school/ undergraduate level Physics/Math courses for a decade now.

Research Interests

Ram Chandra's research interests include Semiconductor/Solid State Physics, Deep UV optoelectronic devices utilizing ultra-thin quantum disks and Bio-inspired luminescent material, 2-D materials, and photonic crystals. Deep UV optoelectronic devices based on III-nitride and novel materials is the main focus of his research.
