Ph.D. 2001, Tel Aviv University, Israel
At IOLR since 1992

Research interests:
Fish and marine invertebrate reproductive physiology, including mechanisms that control sex differentiation, environmental and hormonal cues that initiate and regulate sexual maturity and in vivo/ in vitro procedures that promote gamete maturation and fertilization; focusing on development of methodologies and technologies for efficient broodstock management of various invertebrates (e.g. sea urchins and sea anemones), and finfish (e.g seabream, sea bass, grey mullet, grouper and bluefin tuna).
