Welcome to the “de Roode” Lab

We are in the Department of Biology and the Population Biology, Ecology and Evolution graduate program.

We study the ecology and evolution of infectious diseases. Much of our work focuses on monarch butterflies, which use medicinal plants as a form of medication. We ask how bee-keeping practices may select for more harmful bee diseases, study how within-host competition between malaria parasites affects the evolution of drug resistance. In addition to these disease-related topics, we also study the genetics of monarch butterfly migration.

RESEARCH HIGHLIGHTS

Monarch butterflies in eastern North America migrate to Mexico but those in western North America migrate to the Pacific Coast in California. Our paper in Molecular Ecology shows that these butterflies have different flight ability but are genetically indistinguishable.

Elevated carbon concentrations, as occurring through current climate change, can result in a loss of medicinal properties of milkweeds. See our paper in Ecology Letters.

Infectious diseases play a major role in the ongoing honey bee crisis. Insights from ecology and evolution may provide novel tools to mitigate these disease threats. See our review in Nature Ecology and Evolution. Our paper in PLoS One shows that simple changes to apiary designs can reduce mite spread and increase honey production.

Drug-sensitive malaria parasites suppress resistant parasites in human infections, potentially slowing down resistance spread. See our papers in Proceedings of the Royal Society Series B and PLOS Biology.

A second trip to St Marks resulted in many additional butterfly encounters. It seems the monarchs were late this year but they did arrive in numbers! ... See MoreSee Less

Covid prevented the 2020 monarch butterfly festival in St Marks but we continued our yearly parasite monitoring. Due to Covid we had no big lab crowd this time but Jaap was accompanied by a nine-year old helper. ... See MoreSee Less

We study the ecology and evolution of infectious diseases, asking why evolution has favored parasites that are harmful to their hosts, and how hosts protect themselves against infections.
