Background

After obtaining a Diploma in Biological Sciences from the Christian Albrechts University (CAU), Kiel, Germany in 2002 with research undertaken at the Max-Planck Institute for Limnology (MPIL), Ploen, Germany on aquatic microbial food webs, I received an internship to conduct research on chemosynthetic ecosystems in the Fisher Deep-Sea Lab at the Pennsylvania State University, USA. Returning back to Germany I pursued a PhD in Biological Sciences completed in 2006 at the MPIL in Ploen exploring carbon cycling in lakes and associated microbe-invertebrate interactions. I then moved to the UK to take up a Marie Curie Research Fellowship (Transfer of Knowledge) at The University of Sheffield, UK where I studied microbes in engineered ecosystems. After being awarded one of the prestigious Feodor Lynen Research Fellowships from the Alexander von Humboldt Foundation I moved to New Zealand in 2009 to work at The University of Auckland on the microbial ecology of sponges. I have been a Teaching Postdoctoral Fellow at Massey University in microbial genetics and ecology since 2011.

Research

I am interested in the ecology and evolution of eukaryote - microbe interactions, focusing on symbiotic associations and predator - prey relationships.

Central to my present research is a project exploring the interactions between eukaryote hosts and their associated microbes, particularly the breakdown of mutualistic relationships and pathogen evolution in the sea. There is growing evidence that environmental change enhances the risk of mutualistic breakdowns. Warmer water bodies correlate with emerging diseases leading to substantial mortality among hosts in marine ecosystems, with microorganisms causing a large proportion of these diseases. I am using Vibrios as a model to examine these relationships. Vibrios, which are highly abundant in aquatic environments, are well known for their diverse interactions with their eukaryote hosts, ranging from symbionts to pathogens. Thus understanding the factors that threaten theses mutualistic interactions is essential for conservation and the aquaculture industry alike.
