Marine Conservation Physiology

Understanding how marine organisms function in their environment and respond to environmental change.

Current Projects:

  • Physiological responses to climate change
  • Adaptation mechanisms in marine species
  • Conservation strategies for threatened species

Shark Research

Investigating shark nursery habitats and the impact of environmental changes on shark populations.

Current Projects:

  • Shark nursery habitat mapping
  • Environmental impacts on shark development
  • Conservation of shark populations

Coral Reef Ecosystems

Studying the complex interactions between reef fish and their changing environment.

Current Projects:

  • Reef fish physiology
  • Climate change impacts on reef ecosystems
  • Coral reef conservation
