About Me

I am currently a Senior Lecturer at the Department of Mathematics, University of Peradeniya. I graduated from the University of Peradeniya in 2010 with a Special Degree in Mathematics. Later, I joined the University of Florida, USA, for higher studies in Aug-2011 and completed my PhD in 2017. My research interests are Topology, Geometry and their Applications.
