**Research**

**Research interest**

*My postgraduate research was about developing a mathematical model for the transmission of Lymphatic Filariasis, which is a mosquito-borne parasitic disease. Model validation, model-based analysis, computational tactics were investigated in that work. Such research covers both pure and applied mathematical contexts, which is an interesting pathway for research in Applied Sciences. I continue doing research in Mathematical Epidemiology studying dynamics relevant to disease transmission. In addition, I am interested on other arenas of Mathematical Modelling (eg. Mathematical Biology, Applications in Physics, Applications in Economics/Finance, etc.). Development of mathematical tools to cope with modelling strategies and statistical analysis is a specific interest. Differential Equations (ODE/PDE), Numerical Methods, Optimal Control and Mathematical Computing are the key subject fields that contribute to and benefited from research in modelling.*

**Research experience**

- Obtained a postdoctoral research training in Mathematical modelling of infectious disease transmission at Mathematics Institute, University of Koblenz, Germany – 2019 (Grant: NSF Overseas Special Training Programme)

- Obtained the Degree of Doctor of Philosophy (Ph.D.) in Mathematics from University of Sri Jayewardenepura – 2011. Thesis: Mathematical analysis of parasite dynamics of Lymphatic Filariasis using range modelling and other approaches in relation to observational data from Sri Lanka
