Research
My research interests are to study 1) climatic and anthropogenic forcing on sedimentation in lacustrine and coastal systems, and 2) sedimentary processes of micro plastic litter in aquatic environments. My current focus is to understand climate-catchment dynamics as well as sediment transportation and accumulation in various geological environments in detail.
