Research interests

I am a freshwater biologist with a particular interest in the taxonomy and ecology of aquatic fauna (e.g. microscopic animals such as ciliates and meiofauna). My past research has always focussed on testing theoretical ecology on assemblages of aquatic invertebrates. I have combined field observations and laboratory experiments in the past to assess assemblage patterns of freshwater invertebrates, but have also used them as model systems for testing general theoretical ecology. I am interested in three main theoretical topics:

1) The contribution of faunal compartments to energy flow within freshwater assemblages;

2) The Metabolic Theory of Ecology (MTE) and size structure of natural communities

3) Biodiversity and Ecosystem Functioning (B-EF).
