Associate Professor


I received a BSc in Environmental Science (University of Applied Sciences Bingen, Germany) where I studied the impact of logging on soil chemical and physical characteristics in the Peace River Lowland, Canada. For my MSc (Resources Engineering, University of Karlsruhe, Germany) I investigated sediment nutrient flow in a mangrove ecosystem in Brazil. For my PhD (Landscape Ecology, University of Goettingen, Germany) I studied the belowground carbon dynamics of a tropical forest in Costa Rica. After my PhD I was a post-doctoral fellow at the University of Wyoming (USA) where I investigated the impact of land use change on soil carbon cycling and trace gas fluxes in Panama. I was a Research Fellow at the University of Goettingen, Germany, investigating the water uptake patterns in tree plantations and cacao agroforest systems in Panama and Indonesia. I moved to the University of Auckland in 2010. 

Research | Current

I am an ecosystem ecologist specialising in the cycling of carbon and water in the soil-plant-atmosphere continuum. Broadly my research group focuses on understanding:

  • the patterns of carbon and water dynamics in forest and native grassland ecosystems, coastal wetlands (mangroves) and urban areas
  • how abiotic and biotic drivers and responses to environmental changes (land-cover change, global warming) affect element cycling within and among ecosystems
  • how plant species identity and biodiversity influence ecosystem functions
  • plant-water interactions
  • the characteristics and drivers of the urban carbon cycle

We utilize a variety of approaches and tools to address these questions, including field-based empirical science, laboratory studies, stable isotope (carbon, nitrogen, oxygen, and hydrogen), biogeochemistry, and remote sensing.
