DrSujeewa De Silva

Dr. Sujeewa De Silva is currenlty a lecturer in the school of Mathematical and Physical Sciences (MaPS), and she was appointed to this position in 2017 having joined UTS in 2014 as a postdoctoral fellow. Sujeewa has completed the “Graduate Certificate in Higher Education Teaching and Learning” from University of Technology Sydney in 2017.
Sujeewa's current research explores the applications of precious metals, their alloys, and compounds in plasmonics and broader nanotechnology fields. A key focus of her work is the fabrication of thin films and nanostructures using advanced deposition techniques. Sujeewa investigates how the dielectric function of these materials governs localized surface plasmon resonances and surface optical responses. By tailoring the dielectric properties, her research aims to finely control light–matter interactions, enabling the design of tunable and efficient plasmonic systems for diverse technological applications. 
Sujeewa received her B.Sc in Materials Engineering (2003) with 1st class honours from the University of Moratuwa, Sri Lanka. After having an industrial exposure on the research and development work at a world known porcelain manufacturing company, she joined the department of Materials Science, University of Moratuwa as a lecturer (2005). Few years later, she moved to Australia to pursue her PhD studies at the University of Wollongong, under the supervision of Prof. Shi X. Dou. Her PhD research was on "Investigating and improving the properties of graphene doped magnesium diboride superconductors". On completion of her studies (2013), she worked at Institute for superconducting and electronic materials (ISEM), UoW as a associate research fellow continued her work on magnesium diboride superconductors. She has published a book based on her PhD study area in addition to her research publications in reputed journals.
