Research experience and expertise

Radiometric dating                           A gamma radiometric dating lab was setup in 2003 at UCL and has been managed running. Up to now, hundreds sediment and soil cores from different areas around the world have been dated.

Trace metal pollution and cycling    Early research involves trace metal and N and P cycling in human directly disturbed lake ecosystems in China, and revealing pollution history by using lake sediments. In recent years, research has been mainly focused on lake pollution derived through atmospheric deposition, including: catchment secondary pollution to the lake; using Pb isotope ratios as indicators to trace pollutant Pb in lake ecosystem (NERC ICP Facility); trace metal budgets in lake ecosystems; trace metal (especially Hg and Pb) pollution history recorded by lake sediments in Europe, China, Uganda and other regions, and their implications in trace metal cycling in atmosphere (Defra, EU, Leverhulme Trust, Royal Society, Royal Geographical Society).  

Lake sedimentation processes       Use of chemical parameters such as trace metal profiles and other sediment features in lake sediments to study lake sedimentation processes.
