I completed my undergraduate studies from the College of Chemical Sciences, Institute of Chemistry Ceylon, Sri Lanka (2012-2015) and University of Sri Jayawardenapura, Sri Lanka (2013-2016). Upon completion of my degrees, I worked as a teaching assistant in College of Chemical Sciences and as a demonstrator in Open University, Sri Lanka for a period of 1.5 years. Meanwhile I was qualified with a postgraduate diploma in Analytical Chemistry from University of Colombo. I was awarded a prestigious Chancellor’s International Scholarship from the University of Warwick to join as a PhD student in 2017.
At present, I am studying for a PhD with Dr. Ross Hatton (graduating in 2021) where my research project is mainly based on lead-free perovskite photovoltaics. The study is focused on developing new materials & device architectures for stabilizing tin perovskite photovoltaics.
