I earned a PhD in Plant Ecology from the University of Basel (Switzerland) in 2009 studying carbon fluxes in a mature deciduous forest under elevated CO2. I stayed on for a brief postdoctoral stint investigating drought responses of forest trees. Following a two-year postdoctoral appointment at the University of Western Australia (2010 – 2012) on the conservation physiology of mediterranean-type woodlands, I took on a full-time permanent position as Quantitative Ecologist/Biostatistician at the New Zealand Forest Research Institute (Scion) working on plant-pathogen interactions and the ecology of invasive wood boring beetles. In February 2017, I joined AUT as Senior Lecturer in Ecology.

Teaching Areas:

Research Areas:

Plant ecology, tree physiology, plant-insect interactions, plant-pathogen interactions, insect ecology, global change ecology

Research Summary:

My research ranges from fundamental to applied ecological questions with a focus on tree water and carbon relations, insect ecology and plant-pathogen interactions. I use a variety of physiological approaches and have a strong background in modern statistical modelling techniques.

I am currently investigating the physiology of natural root grafts in kauri and water relations in mangroves. Moreover, I am involved in two Scion-led MBIE funded research projects concerned with i) biosecurity threats of plant pathogens to New Zealand’s primary agricultural, horticultural and forestry industries and natural ecosystems (‘Healthy Tress Healthy Future’ programme), and ii) developing sustainable solutions for insect pest management to meet the requirements of overseas markets for timber, plant and wood product exports (‘Market Access’ programme).

Current Research Projects:

Ecophysiology of kauri
Kauri dieback – Efficacy of anolyte against Phytophthora agathidicia)
Water relations in mangroves
Tree responses to drought
Modeling insect development rates
Competition among invasive and native insect species
