Biography

My work is driven by a long-standing passion to understand and mitigate the impacts of climate change and human activities on marine ecosystems. Early in my career, I investigated the ecological effects of dive tourism on coral reefs and examined how projected greenhouse scenarios influence the early life stages of reef-building corals. These studies sparked my broader interest in how environmental change shapes the resilience of marine organisms.

During my doctoral research, my expertise expanded into marine biogeochemistry and molecular ecology through the study of the calcifying microalga Emiliania huxleyi. Using isotopic, proteomic, and transcriptomic approaches, I explored the physiological and molecular mechanisms that regulate calcification in marine plankton and their responses to changing ocean conditions.

Over the past decade, my research has increasingly focused on coral reef ecosystems. In the Red Sea, I conducted four years of intensive reef surveys across environmental gradients, leading scientific diving expeditions and contributing to large-scale monitoring efforts aimed at understanding how temperature, water chemistry, and regional oceanography shape benthic reef communities.

My work has also included teaching and research in the Western Indian Ocean, particularly in the Seychelles, where I lectured in marine ecosystems and sustainability, for example. There, my research explored ridge-to-reef perspectives on coastal management, interactions between seagrass and coral reef systems, and the timing and ecological significance of coral mass spawning events.

Currently, as part of the Coral Symbiomics Lab, my research focuses on coral thermal resilience and adaptive capacity. This work integrates coral reproduction studies, selective breeding approaches, optical phenotyping, and experimental ecology to better understand and enhance coral resilience under climate change. Alongside research, I contribute to the planning and implementation of interdisciplinary conservation projects that bridge fundamental science with applied reef management.

Across my career, I have aimed to combine field ecology, molecular tools, and collaborative conservation practice to develop solutions that help safeguard marine ecosystems in a rapidly changing world. I am passionate about strengthening Ocean Literacy and environmental conscious decision making in every day live, "Individually, we are one drop. Together, we are an ocean" (Ryunosuke Satoro) of positive change.

Research Interests

My research explores how coral reef ecosystems respond to climate-driven environmental change, integrating coral ecophysiology, resilience mechanisms, and environmental gradient analysis. I am particularly interested in in situ selective breeding and assisted recovery approaches as tools to enhance coral adaptive capacity. Ultimately, my work aims to bridge organismal biology and ecosystem-scale conservation strategies to support resilient coral reef systems.
