Funded PhD: Quantifying Animal Movement Patterns and Behavioural Interactions in a Changing World University of Bristol in United Kingdom

This fully funded PhD project explores the quantification of animal movement patterns and behavioural interactions in a changing world, integrating advanced mathematical modelling with rich empirical datasets. The research addresses fundamental questions in ecology and behaviour, focusing on how animals use space and interact with their environment and each other, especially under the influence of human-driven environmental changes.

The project leverages recent developments in lattice random walks to analytically determine spatio-temporal dynamics of interaction processes between moving entities. This approach aims to provide novel insights into animal interactions, moving beyond traditional stochastic simulations that are computationally intensive and prone to large fluctuations. The integration of empirical data with modelling allows for parameterisation and testing of predictions, enhancing the realism and impact of the research.

The PhD is structured as a joint Cotutelle arrangement between the School of Biological Sciences at the University of Bristol (UK) and the School of Natural Sciences at Macquarie University (Australia). The student will spend the first half of the PhD at Bristol, hosted by Prof. Andy Radford, and the second half at Macquarie, hosted by Prof. Simon Griffith. Prof. Luca Giuggioli (Engineering Maths, Bristol) will provide expert guidance in analytical movement modelling, drawing on his background in statistical physics.

Key research components include the development of state-of-the-art models to assess animal movement in heterogeneous landscapes and predict encounter probabilities. The project utilises two extensive datasets: one from a long-term study of wild zebra finches in Australia, involving automated tracking of over 120 birds, and another from the Dwarf Mongoose Research Project, with year-round monitoring of multiple wild groups over 13 years. These datasets enable investigation of environmental and social influences on movement patterns, spatial cohesion, intragroup dynamics, intergroup conflict, and the effects of vegetation and climate.

There is also an opportunity for fieldwork in Australia during the second half of the PhD, allowing the student to test modelling predictions and further analyse movement data. Candidates should have strong mathematical and computational skills, proficiency in statistical analysis, and ideally some fieldwork experience.

Funding is comprehensive: University of Bristol provides a 42-month tuition fee (split between EPSRC funding and Faculty fee waiver), a 21-month stipend at UKRI rates, and a £2,000 research training support grant per annum. Macquarie University offers a 36-month tuition fee scholarship, a 21-month stipend indexed to the Australian CPI (AUD $39,700 in 2026), and an airfare allowance up to AUD $4,000. Note that overseas students must pay the fee difference and some costs (such as extension/resubmission fees) are not covered.

Eligibility requires meeting admission and scholarship criteria for both universities, not holding or being matriculated for a doctoral degree elsewhere, and satisfying English language requirements. Prospective candidates should submit an Expression of Interest (EOI) via email to both supervisors, including CV, academic transcripts, and a statement of fit for the project. Formal applications to both institutions will follow, with a research proposal and personal statement. The application deadline is April 19, 2026.

For further information or queries, contact the supervisors or the Bristol postgraduate enquiries team. This is an exceptional opportunity for students interested in animal behaviour, ecology, mathematical modelling, and interdisciplinary research across two leading institutions.
