    Dr. Rajbhandari joined Coventry University in November 2015 and is currently working as a Lecturer in School of computing Engineering and Maths. He obtained his bachelor’s degree in Electronics and Communication Engineering from Institute of Engineering, Pulchowk Campus (Tribhuvan University), Nepal in 2004. He obtained an MSc in Optoelectronic and Communication Systems with Distinction in 2006 from Northumbria University and was awarded the P O Byrne prize for the most innovative project. He then joined the Optical Communications Research Lab (OCRG) at Northumbria University as a PhD candidate and was awarded a PhD degree in 2010.He then worked at Northumbria University as a senior research assistant (Dec. 2009-Aug. 2012) and research fellow (Sep. 2012- Dec. 2012). He joined the University of Oxford as a posts-doctorate Research assistant in Dec. 2012 and worked on EPSRC's Ultra-parallel visible light communications (UP-VLC) project which was a collaboration between five UK universities.

    Dr. Rajbhandari has published more than 100 scholarly articles in the area of optical communications and is a co-author of a book on “Optical Wireless Communications – Systems and Channel Modelling with Matlab (2012). He was invited speaker in IEICE Information and Communication Technology Forum 2015 at Manchester. He has also served as a local organizing committee member for CSNDSP2010, publication chair for NOC/OC and I 2011 and proceeding editor for EFEA 2012 and NOC/OC and I 2011 as well as reviewer for several leading publications including the IEEE, OSA and IET journals. His research interests lie in the area of optical wireless communications, modulation techniques, equalization, artificial intelligence and wavelet transforms. He is a member of IEEE and an associate member of the Institute of Physics.
