Biography:

I have studied biology and statistics at the universities of Basel and Neuchâtel, Switzerland. I also undertook an Honours thesis in coral reef ecology at James Cook University, Townsville, where I also gained my qualifications as a dive instructor. After working for one year as a Science teacher on a superyacht, I have returned to academia, working under the supervision of Christian Körner at the university of Basel, where I completed my PhD in 2006 on the physiological responses of mature forest trees to elevated atmospheric carbon dioxide. Six years of post-doctoral studies  at the University of Basel (2 years) and ETH Zurich (4 years) followed. I have been at AUT as a Senior Lecturer since June 2012, and as an Associate professor since 2016.

Research Summary:

I have worked on a large range of ecological topics both in marine and terrestrial environments, using a variety of experimental and computational methods. My original background is in marine ecology, but I have mainly worked in terrestrial environments in the past fifteen years. I am interested in fundamental ecological questions such as:

  • What limits plant growth in various ecosystems?
  • How do global changes impact on ecosystems, particularly plants?
  • How do the global carbon and water cycles interact via vegetation cover?
  • How can meta-analysis and ‘pattern analysis’ help to understand global change impacts on our ecosystems?
  • How can we model plant growth to predict changes in the future carbon cycle?
  • How do trees transport water? How can we measure it?
  • How do trees die under drought?
  • Why do organisms pursue a given resource allocation strategy?

Current Research Projects:

  • The life of a leafless kauri stump: the role of root grafts in tree water relations
  • The ecophysiology of the grey mangrove Avicennia marina
  • Plant growth: what is it? How do we measure it? Why?
  • Sink vs. source limitation in global vegetation models
  • The timing of rainfall events and its role under elevated CO2
  • Grow fast, die young: the consequences for global carbon stocks
  • New ways of measuring sap flow in trees, how can we use electropotential signals?

Schedule:

Together with a team of researchers, I will be organising the 2021 iLEAPS Science conference in Auckland, I am looking forward to this exciting opportunity to bring researchers in my field to a large conference in Auckland!

Awards:

  • 2014 Vice Chancellor Awards, Emerging Researcher ($12,000)
