For doctors looking for research in the field of demography and with a constitution for travel, a job opportunity:

The Oxford Institute of Population Ageing is seeking a quantitative researcher to
work with Dr George Leeson in collaboration with Dr Mike Bonsall (Department of
Zoology) on the Oxford Martin Future of Food Programme. Main responsibilities will
be to conduct population modelling scenarios. As part of the scientific team at the
Institute, the incumbent will be asked to contribute to research tasks related
demographic and statistical analysis. This is an exciting opportunity to contribute to
the development of a world-leading research programme.

The successful candidate will work within a multi-disciplinary project which combines
the expertise of two departments at the University of Oxford, the Oxford Institute of
Population Ageing and the Department of Zoology, to address two key elements of
the food security debate: the changing demography of agricultural populations and
the impact of environmental change.

The contribution of the Research Fellow in Demography is to undertake population
modelling scenarios, primarily on human populations, but also to explore similar
modelling with insect populations. While an interest in the demography of developing
countries is expected, and knowledge of the demography of the Asian region is
desirable, the ability to work in an inter-disciplinary environment alongside both
demographers and biologists is essential. The project will require both independent
work as well as working as part of a multi-disciplinary team. You will also be
expected to participate in project research meetings, seminars and public events.
