I am a Research Fellow in the Environment and Health Theme within the Institute of Environment, Health and Societies.

My main interests lie in aquatic biology, specifically how anthropogenic stressors, such as environmental contaminants, can alter an animals' development, reproductive and immune systems (endocrine disruption). My focus has been to investigate environmental chemical disruption to fish and freshwater gastropod molluscs. Originally the emphasis of my research was on disruption to classic sex steroids (oestrogens and androgens), however recently my attention has been widened to include disruption to other parts of the endocrine system including thryoid and retinoid systems.

Working in the field of endocrine disrupting chemicals one area of research which I am motivated to investigate is mollusc endocrineology. Much of my work with gastropods has found that, contrary to long held views, molluscs may not use the same sex steroids as vertebrates. Without understanding how these fundamental developmental and reproductive processes work in molluscs, this huge and diverse group of animals are at risk of not being adequately protected using the current environmental endocrine disruption testing and legislation.
