Kort presentation
Min forskning är främst inriktad på hur lokala processer samverkar med storskaliga processer (t.ex. spridning, storskaliga väderfenomen) på populationsdynamik och samhällsstruktur. För närvarande har jag tre huvudsakliga forskningsområden:
1. Stokastiska och deterministiska effekter på Daphnia samhällen i hällkar
2. Mikrobiell meta-samhällsstruktur
3. Genetisk variation och resursdifferentiering hos sötvattensfiskar
