Thesis Title: Variations in trace element geochemistry and chemical weathering intensity captured in clastic sedimentary records

Supervisor: Dr. Michael Babechuk

Research Interests: My research aims to develop new geochemical-based understanding of how trace element cycle through Earth’s surface environments and how these cycles evolved through time as a function of long-term, global climate change. I am particularly interested in deciphering the interplay between chemical weathering signatures and variations in source composition recorded in the trace element chemistry of modern clastic sediment and ancient clastic sedimentary rocks. My project involves three facets which include the developments of new sample digestion methods, examination of geochemistry of modern sediments from different fluvial catchments in Newfoundland, as well as comprehensive studies of ancient sedimentary records back to the Proterozoic era (e.g., the clastic sedimentary rocks of the 2.45-2.22 Ga Huronian Supergroup in Ontario/ Quebec).

About Me: I obtained my B.Sc. (doble major in Geology & Earth System Science) at the University of Hong Kong (HKU) and M.Sc. (in Geoscience) at University College of London (UCL) in England. I also worked as a graduate geologist in geotechnical consultancy focusing on natural terrain hazard studies for two years in Hong Kong.
