Postdoctoral researcher Tuomas Aivelo is disease ecologist and evolutionary parasitologist. He has studied both small mammals and their pathogen vectors and developed new methods for identifying parasites and study their co-occurrences within host individuals. He defended his PhD thesis "Longitudinal monitoring of parasites in individual wild primates" in University of Helsinki in 2015 and then did his first postdoctoral project with tick microbiota in Barbara Tschirren's group in University of Zürich, Switzerland. He joined HURP in January 2018 to start the ecological and parasitological aspects of the project.

At the moment, Otso is also involved in research project which surveys the damages caused by rodents in agricultural setting and pathogen spread in domestic-wild animal interface.

Esa Koskela is university lecturer evolutionary ecology in University of Jyväskylä. He has studied especially evolutionary ecology and life history by using voles as a model species. Lately, he has also expanded to studying mechanisms sustaining genetic polymorphisms and epigenetic variation in the nature.
