I am a researcher at the Aquatic Research Facility.

My work mostly spins around corals and coral reefs - this means I can either work on our organisms in the Aquatic Research Facility or I work on samples directly from coral reefs. Mostly the projects that I am working on deal with corals in the face of climate change - as (sea) temperatures increase we lose more and more corals that are sensitive especially to temperature changes.

Currently I am researching on the complex interactions between corals and their microbiome - a complex suite of closely associated microbes that play a fundamental role in coral wellbeing. 

Research interests

I am interested in coral (reef) functioning. While it is important to understand coral reefs on an ecosystem it is my primary interest to learn more about the physiology and molecular machanisms of it's framework builders - the coral.

Membership of professional bodies


Recent conferences

In the recent years I have been able to present project at different locations:

International experience

During my Master Thesis I have worked on coral ecotoxicology at the Australian Institute of Marine Sciences (AIMS), Townsville. During my PhD at KAUST, Saudi Arabia, I mainly focussed on Red Sea corals and contributed to the international “Tara Pacific” expedition researching Pacific coral reefs from Fiji to Japan. My previous postdoc in Hong Kong focussed on coral and coral reef biodiversity in the South China Sea.

In the media

The Tara Pacific expedition was accompanied by a professional outreach campaign to raise awareness for the current state of our ocean. I had the chance to support Tara’s activities for TV and radio interviews as well as in outreach talks.


Our recent projects on coral resilience and restoration has also been presented by the University of Derby in this interview.
