Research Interests

I am primarily interested in the reproductive physiology of corals and the environmental stressors that can disrupt coral reproduction. Specifically, I am interested in the role of steroids in coral reproduction, and in the effects of rising ocean temperatures and pollutants on the reproductive cycle. I conduct my studies on corals from the Gulf of Aqaba, which can withstand water temperature anomalies that cause severe bleaching in most corals around the world. I also explore how formal and informal diplomacy can support collaborative transnational scientific research and conservation. Previously, I focused on reproductive outcomes in humans. As a physician and researcher, I studied how acute maternal stress and stress hormone levels during pregnancy affect birth outcomes and the long-term health of offspring. I also studied the effects of advanced paternal age on reproduction. This background informs my coral research because certain aspects of reproduction, such as reproduction-associated steroids, are highly conserved throughout evolution.
