I am interested in how environmental factors and the presence/absence of key species drive and constrain consumer-resource interactions and the resulting ecosystem dynamics. The studied environmental factors include nutrient and light supply, turbulent mixing, and water temperature in freshwater lakes and marine environments, as well as physical transport processes and disturbances in streams. Study organisms include planktonic and benthic algae, bacteria, protists, planktonic microinvertebrates, benthic macroinvertebrates, fish, and water birds.
Dynamic systems behave often in unexpected ways. Where possible, I therefore translate assumptions into mathematical models from which I derive expectations. Assumptions and predictions of these models are then tested and refined in an iterative process involving field and laboratory experiments and, to a lesser extent, comparative field studies.
