Before joining the InnoDC project, I worked for more than 5 ½ years as a Transmission Planning Engineer at Ceylon Electricity Board (CEB), the largest Electrical Utility in Sri Lanka.

I obtained First Class honors in my BSc.Eng degree, then completed an MSc.Eng in Power, Energy Systems and High Voltage, both at University of Peradeniya (UOP), Sri Lanka.  I specialized in Electrical and Electronic Engineering, and was in the cohort’s top 5-10% during my undergraduate studies.  I was awarded the Prof. E.O.E Pereira Gold Medal for the most Outstanding Engineering Graduate at the General Convocation 2012.

In addition, I am a certified Chartered Electrical Engineer (CEng) of the Institution of Engineers, Sri Lanka (IESL) and a member of IEEE (Institute of Electrical & Electronic Engineering).

I was motivated to carry out research during my undergraduate project on developing an MPPT (maximum power point tracking) controller to harness rooftop Solar PV.  My interest was reinforced through employment-related research projects carried out as a Transmission Planning Engineer and a Teaching Assistant at the Power Electronics Laboratory, UOP.

I aim to develop tools to analyze techno-economic viability of different offshore DC collector platforms in order to evaluate optimum configuration to aid development of Offshore Wind Power Plants on a larger scale.  I strongly believe that the InnoDC project will deliver beneficial outcomes to the scientific community in the future.

After completing this project, I wish to continue my research into HVDC systems, particularly related to offshore wind power integration.  My ambition is to become an expert in the field of HVDC technology – specifically related to renewable integration – and to investigate innovative solutions to improve renewable energy absorption capabilities in different power systems, leading to a greener, cleaner and sustainable power system.

Apart from my academic life, I have been actively involved in IEEE activities and have held distinguish positions in IEEE Sri Lanka Section & Power and Energy Society Chapter, including Assistant Secretary and Professional Development Chair (2015/2016).

Further, I have been playing table tennis since childhood, and led my company table tennis team as Captain, and UOP team as Vice-Captain for several years.  In my spare time, I like listening to music and spending time with my friends and family.
