During my first year as an undergraduate at the University of Peradeniya, I followed Geology, Chemistry and Physics and was selected to the Special Degree programs in Geology and Chemistry. I decided to choose Geology for specialization due to extreme interest in Earth Sciences. I completed my Bachelors Degree in December 2017, with a final year thesis component on 'Geochemical Behavior of Arsenic in Northwestern Sri Lanka'. Afterwards I worked as a teaching assistant at the Department of Geology of UoP, and extracted knowledge on paleoenvironmental studies at the geochemistry laboratory until December 2018.
I started my work as a PhD candidate at the Research School of Earth Sciences in March 2019. My research project aims at investigating the African monsoon variability and humidity/aridity fluctuation, and on the reconstruction of "Green Sahara Periods" over the Plio-Pleistocene. Specifically this study will be focused on the time span beyond 3 Ma, using sediment records from ODP site 967 of the Eastern Mediterranean.
