During my first year as an undergraduate at the University of Peradeniya, I followed Geology, Chemistry and Physics and was selected to the Honours 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 First Class Honours. 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 Mediterranean oceanography & African monsoon variability, and on the reconstruction of "Green Sahara Periods" over the Pliocene. Specifically this study will be focused on the time span between 3-5.3 Ma, using sediment records from ODP site 967 in the eastern Mediterranean. Furthermore, evolution of Mediterranean oceanography immediately after the Zanclean megaflood will be investigated.
