Research interests
- Evolutionary approaches to the study of human behaviour
- Patterns and processes of population change in the developing world
- The application of evolutionary anthropology to questions of public health
- Frameworks that facilitate the integration of biological, cultural and environmental data
- Regional focus: Ethiopia, Sub-Saharan Africa
Current Projects
My research interests lie in the field of human behavioural ecology: using concepts from evolutionary biology to explain human behavioural diversity. The study of human behavioural ecology assumes that biology and behaviour can evolve and adapt through natural selection and by maximising reproductive fitness. Furthermore, that these strategies change overtime/space according to different social and ecological circumstances.
The focus of my research has been to use evolutionary ecological approaches to identify child health issues in the developing world, particularly those arising from recent population changes.
- Evolutionary Demography: testing predictions from 'life history theory'
-
An on-going research project investigating the demographic and health consequences of a labour-saving water supply scheme on a rural agricultural district in Southern Ethiopia (funders: ESRC, Wellcome, The Leverhulme Trust):
- Does a reduction in workload effect women's fertility?
- Does this influence child growth and health?
- Does development intervention influence patterns of education & out-migration?
- Human Behavioural Ecology: exploring human parental investment decisions
-
Current projects analysing demographic and anthropological data to explore how local ecology may be influencing reproductive decisions, child-care, marriage and inheritance practices:
- Sex biases: Can a mother's condition influence the sex of her children?
- The role of kin: How and why do grandmothers improve child growth and survival?
- Polygyny: Why do some women marry married men?
- Family structures: Does wealth increase or decrease sibling competition?

Field sites
Arsi, Southern Ethiopia: Since 1999, I have been undertaking anthropological and demographic data collection in a rural agricultural district of Southern Ethiopia; recently this has included collating child growth and child health data from 800 children and undertaking livelihood and time allocation surveys, in collaboration with researchers at Addis Ababa University and University College London.
British Academy UK-Africa Academic Partnership - Bristol & Addis Ababa (2006-2009): A three year British Academy UK-African Academic Partnership Award with Dr Eshetu Gurmu (Institute of Population Studies, AAU) has formalised collaborative links between students and staff interested in population & development issues in Bristol and Addis Ababa Universities. Details of all the activities that students can take part in are advertised on the partnership website www.ukafrica.net
