Invasion Biology Modeling

My research focuses on the development of forecasting, risk, and impact assessment models of non-native species. By combining computational simulations with both biological and sociological data, my research aims to provide decision support to resource managers and policy makers.

With an emphasis on uncertainty quantification through the construction of Bayesian models, I analyze the implications of various human and biological factors on the spread of fresh water invasive species, including: 1) environmental and demographic stochasticity, 2) dispersal network structure, and 3) human behavioural feedbacks to policy decisions. Together, this research provides novel insights into both ecological processes and environmental policy.
