Ottar Bjornstad Lab
I work in the Departments of Entomology and Biology and at the Center for Infectious Disease Dynamics of the Pennsylvania State University. My main interests are population ecology/dynamics and ecological epidemiology with particular emphasis on mathematical and computational aspects. I am also an adjunct faculty in the department of Statistics and carry out research in statistical ecology and in methods for analyzing spatiotemporal data.
Much of my work is of a collaborative nature working with students, postdocs and faculty locally and across universities worldwide. I currently (or recently) work on the ecology of infectious disease; theoretical and empirical aspects of spatial synchrony in population dynamics; Stage-structured dynamics of insects; and more.
If you wish to be part of any of these studies as a student, postdoc or collaborator: Browse on, check out details on the research and contact me.
My work has several interrelated themes:
- Population dynamics – how do the interactions between individuals and between individuals and the environment determine fluctuations in abundance?
- Interactions between species – how do competition, predation and parasitism affect dynamics?
- Spatial dynamics – what causes regional synchrony or asynchrony in fluctuations? What causes regional transitions in population dynamics
- Ecology of infectious disease – how do host and pathogen characteristics affect incidence of disease? Partly as an integral part of (1-4) and partly as a separate research area, I am also interested in the foundations of confronting theory with data. My fifth theme is-
- Ecological statistics – how can we test the theories about spatiotemporal variation using abundance data?
