Fields of interest: 
environmental geochemistry, hydrogeology, groundwater contamination, CO2 geological storage, arsenic, uranium, radon, tracers

I currently work on developing tracers, including SF6, SF5CF3, PFCs, C, H, O staple isotopes, radiocarbon, and noble gases to quantify the transport and geochemical processes of injected CO2 in subsurface geologic formations at the CO2 storage sites. 

I have worked on the biogeochemical reactions of shallow aquifers in response to CO2 leakage from geological storage. The projects include: (1) conducting geophysical logging, pumping test, tracer test, CO2 push-pull experiment and geochemical modeling in bedrock aquifers to understand the mineral dissolution and trace element release rates; (2) investigating microbial activities and their impact on trace metal release; (3) carrying out sediment incubation experiments in the lab to investigate the biogeochemical reactions under abiotic and biotic conditions; (4) developing diagnostic monitoring systems to assess the risk of shallow aquifer contamination from CO2 leakage.

I have also worked on the hydrogeochemistry, risk assessment and treatment of contaminations in groundwater aquifers. The completed and ongoing projects include: (1) determining the occurrence and spatial pattern of arsenic contamination and its association with bedrock geology; (2) understanding the source and mobilization mechanisms of arsenic in bedrock aquifers from interpretation and statistical analysis on chemistry data; (3) testing the feasibility of predicting arsenic contamination in bedrock aquifers using logistic regression models; (4) examining the distribution of arsenic in groundwater, soil, and stream sediment at national, regional to local scales and their associations; (5) investigating the arsenic evolution in individual wells using borehole coring, logging , pumping test, and water sampling with packers; (6) investigating the occurrence, source and mobilization mechanisms of uranium and radon in bedrock aquifers; (7) promoting the well testing and treatment to reduce the public's exposure to contaminants and to improve community health.
