PhD Thesis Title: Predicting the ecological effects of metals in marine sediments

I have recently completed my PhD in the field of Ecotoxicology and Environmental Chemistry (Marine Pollution), studying the fate, bioavailability and effect of heavy metals in marine sediments. My research specifically investigated metal remobilisation as well as the use of chemical measures in predicting ecological effects in mining-impacted sediments, with the aim of informing the development and application of sediment quality guidelines and regulatory assessment frameworks. Fieldwork was carried out across a gradient of metal contamination in the Fal and Hayle estuarine systems, Cornwall, Southwest England. My research was funded by the Commonwealth Scholarship Commission in the UK and supervised by Professor Alastair Grant and Professor Alex Baker. I was also an Associated Student of the EnvEast Doctoral Training Partnership, funded by the Natural Environment Research Council (NERC).

Prior to the PhD, I worked as an Assistant Lecturer in the Department of Animal and Environmental Biology at Abia State University, where I also completed a BSc (First Class Hons.) in 2011. In 2015, I completed an MSc (Distinction) in Environmental Assessment and Management at the University of Salford.

My main research interests are in the environmental risk assessment of chemicals, especially metals in the marine environment. This involves the monitoring of bioavailable concentrations through chemical measurements, bioaccumulation, and passive sampling; the assessment of ecological effects, including field and laboratory assays, biomarker approaches, pollution-tolerant populations and communities, and biodiversity assessments; as well as the development of regulatory guidelines and policies for environmental protection. I have experience working with a range of marine invertebrates.
