Biography

I obtained BSc Hons degree in Physics from University of Jaffna, Sri Lanka in 2010, and MSc by Research and PhD in Condensed Matter Physics from University of Nottingham in 2012 and 2015, respectively. Following my PhD, I worked as a postdoctoral researcher for 3 years at University of Nottingham and 18 months at University of Manchester. I was appointed as a Lecturer in Physics at Keele University in October 2019.

Research and scholarship

I am interested to study the fundamental properties and applications of novel 2D materials. My research focuses on the production, characterization and exploitation of 2D materials especially, III-VI van der Waals layered materials.

During my first postdoctoral position at University of Nottingham, I developed a physical vapour deposition technique for the growth of 2D layers of InxSey on different substrates (SiO2/Si, Mica, Graphite, Graphene, and GaSe). At Manchester, I learned device fabrication techniques and fabricated devices made of Graphene, Boron Nitride and other 2D materials and studied their physical and transport properties with a view to understand their fundamental physics.

Now at Keele, I am developing growth techniques for III-VI layered materials and their heterostructures.
