Personal profile

Description of research and teaching

PhD, PI

Currently, I work as coordinator of University of Helsinki's Wild Animal Phenotyping infrastructure. 

Research at University of Helsinki:

  • I am PI of the Wildlife Ecology Research (WildER) group at Lammi Biological Station. We investigate how animals interact with their environment and each other by researching connections between phenotypes, genotypes, species and communities.  Our work with the Eurasian lynx incorporates aspects from the phenotype to landscape scale to gain a broader understanding of wildlife ecology and forest habitat conservation. Their large home ranges and comparatively low density make the lynx a fascinating species to investigate strategies for acoustic communication. We pioneer non-invasive methods for research and develop and test technology to foster human-wildlife coexistence. 

Other research

  • Morphological diversity, microevolutionary change:

-Parallel evolutionary change of spring and lake populations of amphipod Pallaseopsis quadrispinosa in Finland (with Risto Väinölä)

-Facial morphology correlates of behaviour of modern humans

  • Conservation

Forest integrity effects on mammalian habitat use

Thermal detection of Lapwing nests using unmanned aerial vehicles

Human life history:

  • I am the creator and manager of a large database for human life-history research. The MiKARELIA database has been digitized from records of Finnish forced migrants. This unique database has been central to projects investigating life history consequences of migration. Using large language models we are currently extracting personal information on social activity from this database which promises to give unprecedented opportunity to analyse the influence of social networks on life history in a historic population.  

 Teaching at University of Helsinki:

  • ECGS-024 , Technology in Ecological Research and Environmental Monitoring,   responsible teacher/organizer. 
  • Mammal ecology course (523126), visiting lecturer, Game animal course, visiting lecturer

I have developed the international internship program at LBS. Since it's inception in 2015 this program is quickly growing and provides a much needed study opportunity for exchange and visiting students at UH.

Outreach (YVV)

My research as well as my work at LBS has been featured in many national and international media outlets. I have also been active in the local community, through visits to high school students and making sure the Station is represented at local events. With funding from Nessling and Wihuri foundations I have spearheaded a project to make a new science nature trail at LBS that will give all visitors a chance to get to know the research done at UH and let them have the opportunity to be acitive citizen scientists.
