Areas of Research Interest
- Chemical and Physical Hydrology
- Aqueous Geochemistry
- Contaminant Hydrology
- Biogeochemical and Hydrological Modeling of Surface water-Groundwater Interactions in Hyporheic Zones
Current Research Topics
- Low-temperature aqueous geochemistry and hydrogeology, emphasizing trace element speciation, organic geochemistry and biogeochemical cycling of trace elements (e.g., arsenic, tungsten, manganese, selenium), nitrates and fluorides in the environment.
- Synchrotron spectroscopy in delineating speciation hence bioavailability of essential and toxic trace elements in natural substrates as in sediments and food (such as rice).
- Reaction kinetics and rates of mineralisation in rock-brine and supercritical CO2 reactions in a CO2 injection scenario within saline aquifers; and monitoring water quality in subsurface aquifers via studying geochemical parameters for formation waters including REEs.
- Aqueous geochemistry of formation waters within basaltic lava-tube caves and studying microbiological processes in formation of minerals under low light environments within caves.
