Research Interests

I am a community ecologist with a particular focus on trophic interactions in both belowground and aboveground invertebrate communities. My research centres on three major topics:

  • Global change ecology – impacts of drivers such as land use and climate change on community structure and ecosystem functioning.
  • Food web ecology – using energy flux in food webs to understand ecological impacts of environmental change.
  • Biodiversity and ecosystem functioning – investigating the relationship between biodiversity and ecological processes in multi-trophic systems.

See my Google Scholar page for a full list of publications.

Current Vacancies

There are currently no funded PhD positions available. If you are thinking of pursuing a Master's degree and are interested in the above research topics, please get in contact and we can discuss possibilities for thesis projects.
