PROFILE

By training, I am a micropalaeontologist, and my research interests lie in the fields of Quaternary paleoceanography and paleoclimatology. I study marine sediments from different oceans around the globe to identify past environmental changes based on microfossils (e.g., foraminifera) and other sedimentary proxies.

Sep. 2011-Feb. 2016 Bachelor of Science, University of Ruhuna Matara, Sri Lanka
BSc special on Oceanography and Marine Geology with Second Class (Honor). Thesis on "Characterization of Biogeochemical condition on Kapurella Hot spring, Sri Lanka" (GPA 3.10/4.0)

Sep. 2016-June 2019 Master Degree, University of Chinese Academy of Sciences Guangzhou, China
Master thesis on "Late Quaternary paleoceanographic changes in the northeastern Indian Ocean based on foraminiferal and stable isotopic records" (GPA 3.77/4.0)

March 2021-present Doctor of Philosophy, Institute of Oceanology, Polish Academy of Sciences Sopot, Poland
