I am working as a technical assistant at MPI-SHH, but my current working place is MPI-BGC, Jena. My main task is measuring compound-specific stable isotopes in n-alkane and FAMEs with coupled gas chromatograph isotope ratio mass spectrometer (GC-IRMS system) at the Max Planck Institute for Biogeochemistry. I have gained expertise in lipid extraction and purification, biomarker analysis and compound-specific stable isotope analysis (CSIA). I am proficient in the use and upkeep of analytical instruments mainly GC-FID, GC-MS and GC-IRMS.
I joined with MPI-SHH in November-2021 to measure stable carbon and hydrogen isotopes in n-alkane and FAMEs for the Patrick Roberts research group.
I completed my PhD in Earth Sciences (Dr. rer, nat.) at International Max Planck Research School for global Biogeochemical Cycles (IMPRS-gBGC), Jena in July 2021. During my PhD, I worked as a doctoral researcher at MPI-BGC from 2017 to 2021. My PhD project focused on the multi-proxy reconstruction of South Asian monsoon variability in Sri Lanka during the Holocene.
I earned my master’s degree (MPhil) in Postgraduate Institute of Science, University of Peradeniya, Sri Lanka focused on multi-proxy paleoclimate reconstructions. During my MPhil research project, I worked as an exchange graduate student at Linköping University, Sweden. I received my B.Sc. degree specializing in Geology at the Faculty of Science, University of Peradeniya, Sri Lanka.
