Summary
I am an environmental chemist with research experience in the areas of experimental geochemistry, in particular contaminated site investigation and remediation, environmental sampling, sample preparation and analysis, statistical analysis of large datasets and environmental nanoscience, in particular detection, tracing and characterization of engineered and natural nanoparticles. My work so far focused on chemistry of environmental pollutants, their detection in the environment, interactions within the environment, potential impact on the environment and human health and clean up technologies. I have researched arsenic, heavy metals and engineered nanoparticles, tackling a variety of research questions: What is the mechanism of natural arsenic immobilization in soils in South-West England and what implications this process may have for tackling wide-spread arsenic pollution problems in other parts of the world? Can waste by-products be effectively used to clean up toxic metals at contaminated sites? How does the reactivity of materials change at the nanoscale and what implications this may have for the environment and human health, following increasing use of such materials.
Currently, I am applying skills gained in bulk and spatially resolved (from the micro- to the nano-scale) mineral and chemical analysis of natural and synthetic materials to explore geochemistry of cobalt, an essential element for life and strategic, technology enabling metal. This work is undertaken within the framework of NERC funded COG3 project which aims to develop innovative biotechnology based Co processing and leaching techniques.
