Thermal Modelling of Li-ion Batteries
Thermal analysis and modelling of lithium-ion battery cells manufactured with locally sourced Sri Lankan graphite, supporting the path toward commercial "Made in Sri Lanka" batteries
Mechanical Engineering researcher and educator bridging energy storage, thermal engineering, and space exploration. I model lithium-ion batteries built from Sri Lankan graphite, teach heat transfer and thermodynamics, and contribute to international research on space technology, sustainability, and policy

I am an academic with teaching and research experience in Mechanical Engineering and Physics. I am currently completing my Master of Philosophy in Mechanical Engineering at the University of Moratuwa, where my research focuses on the thermal analysis and modelling of lithium-ion batteries made with Sri Lankan graphite, supported by an SRC grant scholarship
Over the past five years I have taught undergraduate and vocational courses in heat transfer, energy conservation, manufacturing engineering, thermodynamics, and refrigeration and air conditioning. My work has included course coordination, assessment design, examination moderation, and mentoring students, as well as contributing to curriculum development and academic quality assurance
Alongside engineering, I am deeply engaged in the global space community. I serve as National Point of Contact for Sri Lanka at the Space Generation Advisory Council and lead Women in Space at the International Space Robotics Society. My research spans small satellites, space debris, planetary protection, space robotics, and space law, presented at the International Astronautical Congress in Baku, Milan, and Sydney
I am also an inventor with two patent applications at the National Intellectual Property Office of Sri Lanka, and I enjoy turning ideas into practical, user-focused designs

A display mount with a fog-emitting mechanism, built for exhibitions and events that want atmosphere as part of how an object is presented.
Connectors at both ends carry power and data whichever way round the cable is plugged in, removing orientation from the user's problem.
This invention generally falls within the broader domain of consumer kitchen appliances, food safety devices, and non-destructive optical testing instruments. This field involves the design, development, manufacture, and use of compact, user-friendly appliances intended to assist end consumers, small food businesses, and hospitality establishments in ascertaining the quality and safety of food items prior to preparation and consumption
