My research focuses on the impacts of O2 and CO2 variability on different invertebrate species of Red Sea coastal ecosystems. As effects from climate change and local anthropogenic impacts often co-occur, I’m particularly interested in the evaluation of ecosystem response to the different stressors, either isolated or combined.
