Dr. Lilantha Samaranayake has been a Senior Lecturer in the Department of Electrical and Electronic Engineering, Faculty of Engineering (FoE), University of Peradeniya (UoP), Sri Lanka since 2007. He has been a Research Fellow in the Kyushu Institute of Technology (KIT), Japan in 2006 and in the Advanced Vehicle Engineering Centre, Cranfield University, UK from 2014 to 2015. He has been on national service in the National Nanotechnology Initiative (NNI) of the government of Sri Lanka under which he served as a Senior Scientist in the Sri Lanka Institute of Nanotechnology (SLINTEC) from 2009 to 2011. He is the Chair of the IEEE Sri Lanka Section in 2010 and is a Senior Member of IEEE. Currently he is the advisor to the IEEE Industry Applications Society UoP Student Branch (SB) and the IEEE Robotics and Automation Society UoP SB. He has been the Director of the Engineering Design Centre (EDC) from 2016 to 2018 and currently he is the Director of the newly established Engineering Technology Incubation Centre (ETIC) in the FoE, UoP.
His research career at KTH started in the area of Distributed Control Systems, which is to deal with Networked Control Systems closed via stochastic communication networks. He moved into Soft Actuators research at KIT with a more material science and mathematical modelling flavor which paved the way for him to enter Nanotechnology. At SLINTEC, he worked on wearable medical devices for vital sign monitoring, Ceylon Vein Graphite inventing a process to produce Carbon Nanotubes (CNT) and a production process for inserting nano particles to slow releasing fertilizer nanomaterials. He spent his first sabbatical leave as a Research Fellow in the Cranfield University, UK, where he worked for the EPSRC funded Developing FUTURE Vehicles (Fundamental Understanding of Technologies for Ultra Reduced Emission Vehicles) project, which is a consortium of 10 leading UK industries and leading UK universities such as the Imperial College, London, University of Oxford, etc. He focused on the degradation control of electric vehicle (EV) powertrain components such as the EV battery and the motor.
He has made 15 indexed journal publications and 40 peer reviewed conference publications with google h10 index of 11.

Dr. Samaranayake initiated the battery-supercapacitor Hybrid Energy Storage Systems (HESS) research at DEEE, where he has developed a laboratory testbed with industry funding to demonstrate the HESS with various control algorithms. The platform is a three wheeler commonly known as Tuk-Tuk, converted into electric powered and renamed as e-Wheeler. The complete eco system to deploy e-Wheelers for the public benefit is being developed both as undergraduate projects and industry funded product target projects. The eco system consists of the novel battery swapping station concept realized through locally developed hardware and IoT infrastructure. The technologies developed for HESS are being experimented for mitigating power generation intermittency problems in solar PV systems.
