Dr. Chami N. K, Patabendige, a material chemist, received her Bachelor of Science (BSc) Degree in Chemistry (2004) from the University of Sri Jayewardenepura, Sri Lanka, and her Ph.D. in Fuel Cell Technology (2011) at University of St- Andrews, UK under the supervision of Professor John T. S. Irvine. In 2012, Dr. Patabendige joined the research group of Professor Francis Quai at University of Strathclyde, United Kingdom as a postdoctoral research fellow. In 2014 she moved to University of Glasgow, United Kingdom for a postdoctoral research fellow. She returned to Sri Lanka and joined the Faculty of Technology at the University of Sri Jayewardenepura in 2016 where is currently working a senior lecturer. Now she is the Head of the Department of Science for Technology.

My current research work is to design, build and test new potential sensors for the turbomachinery industry to track the oil condition based on chemical changes. This research involves understanding the current oil sensors and their mechanisms and also understanding the chemical changes in oil over time and extreme conditions. Many laboratory tests, as well as sensors are used to monitor oil conditions. Therefore, I am familiar with absorption measurements (IR, UV-vis), scattering (Raman), fluorescence, elemental analysis (EDX), thermal analysis (DSC, TGA, and DTA), particle counting (DLS) and viscosity measurements. I also do research on material characterizations on rechargeable batteries and fuel cells.  I am also working on solid state synthesis of materials and use of range of structural analysis procedures such as diffraction studies (X-ray, Neutron and electron), TEM, SEM and SAED. I am familiar with structural refinements (using Fullprof and GSAS software), elemental analysis (EDX) and determination of magnetic properties of materials using SQUID. My work also involve determination of electrochemical properties of materials using different techniques such as conductivity and impedance measurements.
