Population ecology and management of the invasive plant, Lespedeza cuneata
… that I used to investigate the persistence and spread of an L. cuneata invasion in a native prairie site. Management treatments reduced local infestations, but failing to treat led to large increases of L. cuneata. Density-based models with even simple spatial information were more predictive …

Exploration vs. exploitation : reducing uncertainty in operational problems
… analysis based on the concept of mean preserving local spread, we show that the structure of the optimal policy generalizes that of the initial model where jobs were homogeneous and had equal weights. Finally, in the third part of the thesis (Chapter 4), we study a broad class of stochastic …

The mathematical modeling and analysis of nonlocal ecological invasions and savanna population dynamics
… forest, and the second involves modeling the non-local spread of a biological invader over heterogeneous terrain while incorporating the influence of a mass transportation network on the system. Both models utilize and compare work done in other, often more opaque, modeling paradigms to better …
