David Walker

David Walker is a Senior Lecturer at the University of Western Australia (UWA), affiliated with the School of Physics, Maths and Computing and the Department of Mathematics and Statistics. His research focuses on complex systems, dynamical systems, and granular materials, with applications in epidemiology, environmental science, and engineering. He holds an h-index of 15 and has published over 86 peer-reviewed articles.

Walker’s research interests include the analysis of granular media mechanics, network science applied to time series data, and mathematical modeling of biological systems. His work contributes to UN Sustainable Development Goals related to clean water and climate action through studies on aquifer systems and disease control strategies.

Key contributions include advancements in reservoir computing, network-based analysis of granular dynamics, and epidemic modeling. Recent work addresses mobility data analysis for pandemic control and utilizes ordinal partition networks for time series analysis. His research methodologies often integrate nonlinear dynamics, data compression techniques, and complex systems theory.

Walker has secured seven grants, including projects on animal welfare, smart farming technologies, and network modeling of biological systems. Notable collaborations span institutions like the University of Melbourne, The Hong Kong Polytechnic University, and Bioss.ac.uk. His expertise bridges theoretical mathematics, computational science, and applied engineering challenges.

Despite extensive contributions, no scientific awards are explicitly listed. His work emphasizes interdisciplinary applications, with ongoing projects in livestock health monitoring and geospatial analysis of groundwater systems.
