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. One of the main objectives of my research project aims at investigating the African monsoon variability and humidity/aridity fluctuation, and on the reconstruction of "Green Sahara Periods" over the Pliocene. Furthermore, evolution of Mediterranean oceanography followed by the end of the Messinian Salinity Crisis will be investigated. Specifically this study will be focused on the time span beyond 3 Ma, using sediment records from ODP site 967 of the Eastern Mediterranean.
