I have been at the University of East Anglia (UEA) since 1989. Prior to that I worked in the Institute of Estuarine and Coastal Studies at Hull University, and Dove Marine Laboratory, Cullercoats (Newcastle University). I have a BSc in Marine Biology, and a PhD in Oceanography, both from the University of Wales (Swansea).

In addition to the research and teaching activities detailed below, I am Deputy Head of School and Director of Finance for the School of Environmental Sciences, overseeing the management of a £17M budget and am heavily involved with The Earth and Life System Alliance (ELSA), a strategic alliance between the University and the adjacent John Innes Centre. I have previously been director of the Centre for Ecology, Evolution and Conservation (CEEC), which brings together a large group of ecologists and evolutionary biologists spread across the Schools of Environmental Sciences and Biological Sciences..

Outside of work, I am married to Ruth, with a son and daughter aged 11 and 14, enjoy gardening and walking, and am a member of St Andrew's church in central Norwich.

Research Interests

The ultimate aim of my research in this are is to define the dose-effect relationships relating environmental concentrations of particular contaminants to predictions of their ecological effects. Within this, I have been particularly involved in the use of metal tolerant populations and communities as potential monitoring tools and as model systems to understand the cause-effect chain linking effects of contaminants on individual organisms to their ecological effects on populations and communities. This is increasingly involving me on work linking whole organism and population level effects with so called "biomarker" responses to pollutants. Other interests within this broad area include:

Environmental impacts of manufactured nanoparticles
Ecological risk assessment of drill cuttings piles and the likely environmental impacts of oil rig decommissioning in the Northern North Sea
Use of X-ray fluorescence in monitoring metal concentrations and use of metals as tracers of sediment transport.
Speciation and availability of metals bound to sediments.

Most of my work in this area uses matrix projection models and the mathematical tools developed by Tuljapurkar, Orzack, Caswell, Cohen and others to determine the circumstances in which stochastic variation in survival and/or reproductive success alter optimal life histories and the selection pressures on different parts of the life history. A recent paper (Grant, 1997) shows how elasticity analysis can be extended to any density dependent population model, including those which have chaotic dynamics or experience stochastic environmental variation. A subsequent paper (Grant, 1998) shows how these methods can be used to predict the consequences of chronic toxicity or other perturbation for field populations which experience density dependence. We have developed the theory in more detail in a paper published in a special issue of the journal Ecology on elasticity analysis (Grant and Benton, 2000) and have reviewed the whole field in an article in Trends in Ecology and Evolution (Benton and Grant, 1999). The most important result of this work is the conclusion that a density independent analysis is often a poor guide to the impact of changes in individual demographic parameters on density dependent populations. This means that density dependence cannot be ignored when using elasticity analysis in the management of populations (see my recent paper on Elasticity analysis of LPA model of Tribolium for a worked example that illustrates this). The implications for evolutionary studies are not quite so severe, as a density independent analysis often provides a reasonable approximation to the effects on individual fitness. This is, however, not always the case. However, when populations have density dependent growth and are subject to stochastic environmental variation or show non-equilibrium dynamics, one cannot guarantee that any of the standard fitness measures will give the same conclusions as the fully correct approach using invasibility (see Benton and Grant, 2000). This means that care should be exercised when using lifetime reproductive success as a fitness measure in behavioural ecology. Much of this work is in collaboration with Tim Benton, now at Leeds University. I am also involved in research on some other aspects of the life history biology of marine organisms.

In conjunction with Dr. Mark Rehfisch and Dr. Phil Atkinson of the British Trust for Ornithology (BTO), Dr. Steve Crooks and myself have been involved in carrying out a review for English Nature of the success (or otherwise) of schemes to create or recreate intertidal habitats such as saltmarshes and mudflats. The final report of this work is available on the English Nature web site, and further information on the project is available via this web page. One of my researchers, Hannah Mossman, is continuing this work, jointly supervised by a plant ecologist colleague, Tony Davy.

In November 2009, there were over 1700 citations of my papers in Science Citation index.

PhD Opportunities

The School of Environmental Sciences has a number of PhD studentships available each year. I have a PhD project available with colleagues at the John Innes Centre carrying out mathematical modelling of the consequences of molecular processes for individual fitness and population dynamics (see here for details). For other research opportunities in Ecology, please look at the home page of the Centre for Ecology, Evolution and Conservation.

Teaching

My main teaching responsibility is a 200 level course in Coastal and Marine Ecology (ENV 2A02), which focusses on developing student's skills and confidence in using the primary literature. I am also involved in teaching a course (ENV2A7Y) which seeks to develop student's skills in organism identification and to give training in the statistical analysis of ecological data.

I have been course director for our Ecology degree programme, and had a major involvement in planning our MSc in Applied Ecology and Conservation, both of which are run jointly with the School of Biological Sciences. The course units that I teach are also available as part of our BSc Environmental Sciences programme, and have been course director for BSc Environmental Sciences with a year in Europe.
