Parametric and nonparametric approaches to explain and predict nonlinear population dynamics in changing environments
… the control of population health, depend on the dynamics of biological populations within a given environment. Therefore, understanding and predicting the effects of changing environments on the dynamics of biological populations evolving in a continuously changing world is, nowadays, one of the …

Understanding and predicting responses of ecological communities to perturbations
… three main ways. In Chapters 2 and 3, we explore Lotka-Volterra population dynamics at equilibrium and demonstrate that subsets of species that can tolerate a larger amount of perturbations on model parameters (i.e., structural perturbations) are more likely to persist. We then show how these …

Pure and Mixed Strategies in Cyclic Competition: Extinction, Coexistence, and Patterns
… species on different lattice structures using Lotka-Volterra dynamics. We find that the extinction time of a well mixed system goes linearly with respect to the system size and that the probability distribution approximately takes the shape of a shifted exponential. However, this is not true …

Towards bioengineered ecosystems: Three studies in invasion biology
"An important feature of ecosystems is their invasibility, i.e. their resistance to invasion by nonnative organisms. Invasion is a driver of change at scales as small as a bioreactor and as large as the scale of biogeography. Invasion can be either a desired outcome, for example in the use of …
