In my research, I construct theoretical and mathematical models for the spread of invasive species. Currently, I am working on a decision theory model using stochastic dynamic programming (SDP) which incorporates a spatial spread model for leafy spurge (Euphorbia esula). The objective of this project is to find the optimal control strategy (biological, chemical or multi-species grazing) in a given time which maximizes the benefits in the next time period. This project will assist policy makers and land managers in deciding which control strategy to employ at any given time under the assumptions in our model. |
|
To solve such problems I will be using theoretical, mathematical and computational tools along with empirical data to validate my models. Computer programming will play a large part in my work in the Leung lab. Some other research paths I may wander off to may include philosophy of ecology/biology, social science and policy making in biology. |

My area of interest is in the development of forecasting and risk assessment models of non-native species. Computationally intensive methods for forecasting within a regime of high uncertainty have become increasingly feasible with the decreasing cost of high powered computers. |
The second portion of my course of study will be carried out in collaboration with the Department of Fisheries and Oceans. The department is interested in forecasting potential invasions of aquatic flora and fauna to the Great Lakes Basin. Formulating an integrative model across all known pathways of introduction will be the crux of this project. |

My proposed topic of research for my thesis is to develop new theoretical options to manage invasive species. One half will focus on eradication strategies: presently, there are few general frameworks for managers to eradicate an established invader. We aim to develop new strategies for this common problem, explicitly incorporating the parameters of most use to managers such as feasibility, cost, timescale, and scope allowing them to most easily and quickly make decisions. The second half will concentrate on monitoring for range expansions and new aquatic invasions. This will provide managers a framework to devise cost-benefit-optimized monitoring strategies for their aquatic system. Further, I'm am involved on several projects involving development of spatial statistical methods, as well as spread modeling of invasive species incorporating oceanographic data.
