Angus Webb is a quantitative ecologist in the Environmental Hydrology and Water Resources group within the Department of Infrastructure Engineering, University of Melbourne. His research focuses on the study of landscape-scale impacts of human-induced disturbances on freshwater systems, and what can be done to restore these systems. Quantitative ecology is the use of maths and statistics to try to make sense of our natural environment, or to try to make predictions about individuals, populations or ecosystems. Currently, we spend a lot of money collecting data, but not getting maximal value from this investment. Through more advanced analytical approaches, we can often gain additional insight into these complex environments.

Current research includes:

  • Ecological responses to changes in river flow regimes, focusing on data collected under the Victorian Environmental Flows Monitoring and Assessment Program and the Commonwealth Environmental Water Office long-term intervention monitoring program
  • Bayesian analysis of large-scale environmental data sets
  • Modelling effects of habitat network topography on populations and communities
  • Causal Criteria Analysis as a means of systematically analyzing the knowledge in existing literature
