### Edinburgh Group - physical sciences

#### Graeme Ackland (PI)

Graeme Ackland holds a chair in Computation Simulation in the School of Physics at the University of Edinburgh and leads the NANIA group. While much of Graeme's early work concerned condensed matter physics, he has more recently become interested in the statistical mechanics of complex, open, non-equilibrium systems.

Recent articles of interest include:

- G.J.Ackland, Devil's staircase in kinetically limited growth, Phys Rev E 66 (4) 041605 (2002)
- G.J.Ackland and D.Butler, Pack formation in cycling and orienteering, Nature, 413, 127 (2001)

#### Tim Lenton (PI)

Tim Lenton is now based at the University of East Anglia as a Reader in Earth System Analysis. His research into complex systems spans the scales from ecosystem to planetary. His work on the theory of Earth as a self-regulating system covers the history and future of life on Earth, and includes work on the Daisyworld model and other generic models of life-environment feedback.

Recent articles of interest include:

- Lenton, T. M. and D. M. Wilkinson, Developing the Gaia theory, Climatic Change 58(1-2): 1-12. (2003)
- Lenton, T. M., Testing Gaia: the effect of life on Earth's habitability and regulation. Climatic Change 52: 409-422. (2002).
- Lenton, T. M. Gaia and natural selection, Nature 394: 439-447 (1998).

#### Jamie Wood (PDRA)

Jamie Wood is now in Edinburgh as a Post Doctoral Research Assistant on the NANIA grant. His work is focused on two distinct areas: Firstly extending the Daisyworld model and related models of atmosphere-biosphere interaction. Secondly, looking at the physics of flocking behaviour and other collective biological phenomena. In his previous research existence he was interested in the theory of wetting, in particular at structured surfaces and in extending exact (Ising) solutions in two dimensions.

Articles of interest include:

- Wetting at a grain boundary. D.B. Abraham, Ville Mustonen and A.J.Wood, Physical Review Letters 93 076101 (2004).
- Universal phase boundary shifts for corner wetting and filling. A.O.Parry, A.J.Wood, A. Drzewinski and Enrico Carlon. Physical Review Letters. 87 196103 (2001).

### Edinburgh Group - geological sciences

#### Ian Main

Ian Main has been Professor of Seismology and Rock Physics at Edinburgh since 2000 and his research interests include earthquake source mechanics, earthquake hazard, and the statistical mechanics of earthquake and fault/ fracture populations. This work involves both laboratory experiments and novel numerical approaches to geophysical problems.

Recent articles of interest include:

- I. Main and F. al-Kindy, Entropy, energy, and proximity to criticality in global earthquake populations, J. Geophys. Res. 108, 2521 (2002).

### Edinburgh Group - biological sciences

#### Nick Barton (PI)

Nick Barton holds a chair in the Institute for Cell and Animal Population Biology at the University of Edinburgh and his research centres on understanding the evolution of traits which depend on interactions between large numbers of genes, distributed across spatially extended populations. Such interactions determine the way populations adapt in response to natural and artificial selection, and also the way they diverge to form separate species.

Recent articles of interest include:

- N. Barton et al. Neutral evolution in spatially continuous populations. Theor. Pop. Biol. 61, 31 (2002).
- N. Barton Adaptation at the edge of a species' range. Integrating genetics and ecology in a spatial context, Blackwells, London. (2001)

#### Glenn Marion (PI)

Glenn leads the Biomathematics and Statistics Scotland (BioSS) research team in modelling complex systems and risk. His main research interests involve the stochastic modelling of ecological and agricultural systems in close collaboration with biological scientists, and recent applications include grazing and foraging systems, evolution of pathogen virulence in crops and disease spread in citrus orchards.

Recent articles of interest include:

- X. Mao, G. Marion and E. Renshaw, Environmental Brownian noise suppresses explosions in population dynamics. Stochastic Processes and Their Applications 97, 95-110, (2002).
- G. Marion, X. Mao, E. Renshaw, and J. Liu, Spatial heterogeneity and the stability of reaction states in autocatalysis. Phys. Rev. E 66, 051915, (2002).

### Manchester Group - physical sciences

#### Alan McKane (PI)

Alan McKane is based in the School of Physics at the University of Manchester and works on the statistical mechanics of non-equilibrium systems and the theory of stochastic processes. In particular, he is interested in the application of these methods to theoretical ecology and his "webworld" model incorporates both population and evolutionary dynamics into a model ecology.

Recent articles of interest include:

- McKane AJ, Alonso D, Sole RV, Hubbel's community dynamics model, Theo. Popul. Biol. 65 67 (2004)
- R.V. Sole, D. Alonso and A. McKane. Self-organised instability in complex ecosystems Philos T Roy Soc B 357 (1421): 667-681 2002

### Manchester Group - social sciences

#### Bruce Edmonds (PI)

Bruce Edmonds is a member of the Centre for Policy Modelling and is involved in many aspects of agent-based modelling in social science applications. His expertise lies in what makes self organising multi-agent systems work, the relationship between complexity and simulation and the formal equivalence of computer models of different systems.

Recent articles of interest include:
