I earned the B.Sc. (1st Class Honors) in Computer Science and Engineering from the University of Moratuwa, Sri Lanka in 2004. I obtained M.S. and Ph.D in Electrical and Computer Engineering from the Colorado State University, Fort Collins, USA in 2008 and 2012, respectively. I also have diplomas and certifications in psychology, college teaching, and security products from WatchGuard. I joined the Dept. of Computer Science and Engineering at University of Moratuwa, Sri Lanka in 2005, where I was later promoted to senior lecturer grade I and II in 2012 and 2017, respectively. In 2019 I joined Data61 of the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia. Later in the same year, I also joined the School of Computer Science and Engineering, University of New South Wales (UNSW), Australia as a Conjoint Senior Lecturer. I have also taught part-time at Naval Artificer Training Institute, Sri Lanka and Science Land IT, Northshore College of Business, and Rajarata University of Sri Lanka. My research interests include Distributed Systems (Blockchain, Cloud, and P2P), Security, IoT (Internet of Things), and Data Engineering, as well as multidisciplinary applications of those technologies. I am a Senior Member of IEEE and Member of IESL. I was an IEEE student member (2007-2012), ACM Member (2014-2016), and president of the student leadership council of the NSF Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere (2010-2012). I love to travel, food, and read.
