Research
My research is focused primarily
on biological invasions:
the success, impacts, and sources of introduced
species, across temporal and spatial scales. I work at the interface of
biological and mathematical approaches to understanding invasion
dynamics in marine and aquatic species, and infectious diseases. Some current projects are described here.
Marine and aquatic invasions
Where will introduced species establish?
The chance that an introduced invader will establish depends in part on
how many individuals are introduced, the species population dynamics,
and the influence of abiotic factors. I am developing a modeling
approach to visualise how environmental variables affect population
dynamics in two invasive species on the Pacific coast of North America,
the mitten crab Eriocheir sinensis and the varnish clam Nuttallia obscurata. This work is in collaboration with Mark Lewis at the Centre for Mathematical Biology (CMB), Colin Levings at the Department of Fisheries and Oceans (DFO), and the Canadian Aquatic Invasive Species Network (CAISN).
How can modeling inform our understanding of biological invasions?
Dynamic mathematical modeling has a long history of providing insight
into ecological processes. I am examining the use of mathematical
models in exploring marine invasion dynamics in particular. This work
is in collaboration with Mark Lewis at the Centre for Mathematical Biology (CMB).
Emerging infectious
diseases
How can we best control emerging infectious diseases?
West Nile virus is an introduced,
emerging infectious disease in North America. I am studying how the
underlying assumptions built into epidemiological models of West Nile
virus and other diseases influence the predictions we make for disease
outbreaks and control. This work is in collaboration with Mark Lewisat the Centre for Mathematical Biology (CMB),
Pauline van den Driessche at the University of Victoria, and Joanna Renclawowicz.
