My research focuses on biodiversity loss, with an emphasis on trying to reverse species declines. This is achieved by using ecological concepts to address conservation issues. I have a diverse interest in conservation topics that include studying forest and urban ecology in the United States, wildlife reintroductions and ecology in the Saharan and Arabian deserts, and coral reef fish and shark populations in the Red Sea. I am also involved in long term population studies of the endangered Egyptian tortoise and coral reef fish community in Aqaba, Jordan.
