Levy's main interest is in understanding the role of ‘timing' in marine systems and molecular ecology of marine cnidarians under anthropogenic stressors ranging from climate change to ecotoxicity. In the last few years, Levy has focused on investigating cnidarian biology, evolution, ecology, genomics and biological clocks using marine model systems including symbiotic corals, and sea anemones such as Aiptasia sp. and Nematostella vectensis. Levy gained much relevant experience studying the effects of light on biological clocks in cnidarians, and identifying key processes governed by the circadian clock mechanism such as behaviour, reproduction cycles, cnidarians physiology, genomics at different environmental conditions. During his career Levy has also worked extensively towards identifying and unravelling major processes related to physiology and stress in the Symbiodinium, the symbiotic algae found together with cnidarians. These processes include photosynthesis, pigment synthesis and temporal gene expression.
