George Roff

Dr. George Roff is an Associate Professor in Marine Science at the School of the Environment, University of Queensland, with a prolific research career focused on coral reef ecology and climate change impacts. His work integrates paleoecological approaches with contemporary field studies to assess reef resilience and degradation drivers across the Great Barrier Reef, Red Sea, and Pacific regions.

Research interests center on coral reef dynamics under environmental change, including:

• Climate change thresholds for coral survival
• Coral disease and bleaching mechanisms
• Reef accretion/degradation decoupling
• Historical baselines for reef management
• Connectivity and recovery processes

Analysis of his 15 most recent publications reveals dominant themes in climate refugia viability, carbonate budget modeling, and paleoecological reconstruction of disturbance events. His work consistently emphasizes the narrow thermal limits for reef persistence and the critical importance of 1.5°C warming targets.

His scientific contributions include foundational studies on:

• Coral recruitment dynamics
• Shark trophic cascades
• Reef-scale erosion following mass mortality
• U-Th dating of coral mortality events

Roff leads field-intensive research programs involving benthic surveys, sediment coring, and larval tracking across multiple reef systems. His work directly informs marine conservation policy through IPCC-relevant climate projections and reef management strategies under the University of Queensland's Global Change Institute.
