My research primarily focuses on the biogeochemical cycles of trace elements and the application of their isotope systems in Earth and environmental sciences. Trace elements can be toxic pollutants or vital nutrients that limit the growth of organisms and control the biological evolution of the Earth. I apply high precision elemental and isotopic analysis to study the source, transformation and fate of trace elements.

I am a research associate in Dr. Anbar’s lab. One of the major elements that I have been studying is mercury (Hg), a global pollutant that has received increasing attention. Stable isotope fractionation of Hg is a powerful tool in tracing Hg cycle in the environment. I have been studying the fundamental mechanisms of Hg isotope fractionation during its transformations, as well as tracing Hg cycling at various temporal and spatial scales using its stable isotopes.

In Dr. Anbar’s lab, my role is to support the operation of the lab, contribute to existing research projects and lead new research projects. I maintain lab instruments, help students run their samples and handle external requests for sample analysis or collaborations. I am involved in various projects that study the early history of the Earth using novel metal isotope systems (e.g., Mo and U), and projects that use Ca isotopes in biomedical research. In the mean time, I am developing Hg isotopes as a novel tracer for ocean redox change in early Earth. You can contact me at
