My research typically involves a lead role in collaborations that span multiple fields of science and mathematics, and have included teams of up to twelve researchers. Much of my work is computational in nature and implemented in Python with various efficiency tweaks (parallel processing, GPU computation, C libraries) as needed. Some examples of my code can be found on my Github page.
Currently, my work focuses on epidemic modeling of opioid addiction, wind- and water-based movement of organisms under various behavioral regimes, pattern formation in locust swarms, and the cultural dynamics of bird song. I advise four graduate students in mathematics with one former graduate student starting a tenure-track position in the Fall of 2020.
Past research projects include aerial dispersal of seeds and parasitoid wasps over multiple scales. In the latter case, having formulated a new mathematical model for wasp spread, I developed CUDA powered software in Python that provides meter-scale resolution results over an area nearly 20 km^2 in size. Bayesian inference is used to fit the parameters to field data.
I have also worked on the development of a savanna model that explores how savanna ecosystems are dependent upon various climatic variables and fire disturbance. Using a mathematically transparent model for water resource availability and stand structure, we demonstrated how seasonal rainfall distribution, and esp. seasonal drought, can act as the primary determinant for stand structure through soil water dynamics, with frequent fire disturbance able to reduce population from a climatically stable state.

Anonymous reviewer: "...the methodology is excellent, and the study serves as an exemplar of the use of Bayesian methods to estimate parameters in a mechanistic mathematical model and is applicable to modelling in any field, not just dispersal."
Anonymous reviewer: "I think the paper will be interesting and useful to a broad audience of scientists across an array of fields and fits perfectly with the aims and scope of Journal of Royal Society Interface."
