About

Dr. B. I. Anuradha Mendis is a Senior Lecturer (Temporary) in the Department of Electrical and Information Engineering at University of Ruhuna. He received the B.Sc. Engineering (First Class Honors) degree from University of Ruhuna, Sri Lanka, in 2008, and the M.Sc. and the Ph.D. degrees in Information and Communication Technology (ICT) from University of Agder (UiA), Norway in 2012 and 2016, respectively. His Master thesis was awarded as the Best Master’s thesis in ICT at UiA in 2012. From March 2017 to March 2020, he served as a Post-Doctoral Research Fellow at the Department of ICT, UiA. Much of his work has been on improving the understanding, design and performance of spectrum allocation and reliability aspects of wireless systems, mainly through the application of stochastic process modeling, statistics and performance evaluation.

He spent one year as an engineer at Huawei technologies, Sri Lanka, from Oct. 2008 to Aug. 2009 and he worked as a lecturer at the Department of Electrical and Information Engineering, University of Ruhuna from Aug. 2009 to Aug. 2010. Moreover, he has served as a Session Chair for IEEE ICC conferences, and on the TPC of several international conferences. Dr. Anuradha’s current research interest covers various areas of mobile and wireless communications, including cognitive radio networks, ultra-reliable communication, massive MTC, Internet of Things, modeling and performance analysis of modern communications systems and networks.
