Impacts of global climate change stressors on marine biota

Investigating whether marine species are able to phenotypically adjust, or evolutionarily adapt to a changing climate. Some marine organisms are incredibly robust to climate stress, and I'm keen to understand why! In the lab, I have tested the impacts of a variety of stressors (increased temperature, low pH, decreased salinity) on the developmental stages of a variety of marine organisms.

How exposure to environmental extremes influences animal response to stressors

Investigations of transgenerational and environmental effects in buffering the progeny’s response to climate change using natural model systems. Studying the adaptations animals' use to survive in extreme environments, such as natural CO2 vents which are low pH environments, can provide insight into factors that increase resilience under climate change.

Using technology to improve our understanding of coral reefs & reef restoration

- Integrating remote sensing technologies with in-water surveys and knowledge of species biology, allow an investigation of processes across much larger scales. With more and more freely available remotely sensed data and advances in technology, we can explore much more of the ocean.

Drivers of coral reef health

The worldwide loss of live coral cover and phase shifts from coral- to algal-dominated reefs has sparked various efforts to facilitate coral reef persistence and resilience, where various human and abiotic drivers can impact reef health. Additionally, coral reefs receive input from many land based factors, connecting land-sea management will more efficiently build resilience within and between these habitats.
