Parasitoid Ecology Group

Metapopulation Research Centre

University of Helsinki



We study host-parasite interactions, and processes affecting community structure and dynamics in a patchy landscape.

Our primary research system is the community associated with the Glanville fritillary butterfly Melitaea cinxia in Finland. Within that community we mainly focus on parasitoids and hyperparasitoids, though we also work with related butterflies, their food plants, and endosymbionts.

Interested in joining the lab?

Postdocs, undergraduates and graduate students are invited to join the lab at any time. Please contact Saskya van Nouhuys ( to discuss possible research projects and funding opportunities.

University of Helsinki:  
There are usually interesting projects in our group for bachelor or MSc (Gradu) research. Check out these current projects on parasitoid physiology or plant ecology.

If you are interested in the PhD program check out the  Luova Graduate School page and the  Metapopulation Research Centre page

Cornell University:
Our research group is based at the University of Helsinki.  However, Saskya spends some time at Cornell each year so there is the potential for undergraduate reseach experience in Finland.  Check out the Biology Undergraduate Research web page:

PhD students at Cornell: Saskya can be on your committee, but not be your main supervisor.  Email if you want to talk about it (
