Major Academic/Research Interests

Phytoestrogens, reproductive ecology of dioecious plants, epicuticular waxes, mineral deposits, plant-animal interactions, native plants

Main research interest: Estrogen compounds in plants (phytoestrogens)

The search for phytoestrogens and their possible functions in plant development and reproduction was approached by choosing a specific molecular screening technique, the estrogen-responsive transcriptional system in yeast (Saccharomyces cerevisiae). A variety of cellular, biochemical, physiological, molecular and genetic approaches are further employed, at the microscopic and organism levels to understand the role of these compounds in plant development and reproduction. Research topics include: the isolation and characterization of phytoestrogens from different plant species; the involvement of phytoestrogens in plant development and sexual reproduction and/or reproductive ecology; search for plant endogenous receptors responsive to phytoestrogens; estrogens in dietary plants and food products; medical applications of phytoestrogens for the prevention and therapy of cancer; sexual dimorphism and reproductive ecology of dioecious plants of the mulberry family.

Other research interests:

Plant epicuticular wax biochemistry, deposition and functions; plant mineral depositions and functions; plant-animal interactions; native plants.
