Faculty: Education, Health and Sciences
School: School of Science
Subject Area: Geographical, Earth and Environmental Sciences
I am actively engaged in research and translate the knowledge gained from this into my teaching.
Teaching responsibilities
I teach geology, with particular responsibilities in palaeontology, palaeoenvironmental analysis, Earth history and training in geological fieldwork. I also teach key skills and coordinate final-year independent studies in geology.
Research interests
My research focuses on the use of proxy data from bivalve mollusc shells, both marine and freshwater, to document environmental change. Fine-scale (e.g. seasonal) information can be obtained from ontogenetic (through-growth) records of stable-isotopic composition, trace element concentration and growth-increment width. I have applied this methodology in investigations of the distant (Jurassic) and more recent (Late Cenozoic) past, the results from the latter being relevant to prediction of future climate change.
Membership of professional bodies and advisory committees
Member of the Palaeontological Association; member of PA Council 1999-2003; Handling Editor of Palaeontology 2000-03.
Member of the Higher Education Academy.
