Areas of Expertise

🦎

Amphibian Ecology & Conservation

Life cycle, habitat ecology, and distribution of Salamandra infraimmaculata, Ommatotriton vittatus, and other species across Israel's diverse environments.

🐟

Fish Reproductive Physiology

Brain-pituitary-gonad axis, hormonal regulation, and behavioral-endocrine interactions in Blue Gourami and Russian Sturgeon.

🧬

Molecular Sex Determination

Genetic markers and molecular diagnostics for early sex identification in Russian Sturgeon, with applications in caviar production.

🌊

Aquaculture & Fish Farming

Sturgeon farming for caviar production, closed recirculating water systems, coral aquaculture, and optimization of fish growth conditions.

🔬

Epitranscriptomics

Investigating m6A RNA methylation and other epitranscriptomic modifications regulating gene expression in fish and amphibians across life stages.

🌿

Environmental Adaptation

How aquatic species adapt to semi-arid and arid environments, with field research across the Hula Valley, Upper Galilee, Golan Heights, and Mount Hermon.

Current Projects

🐟

Molecular Sex Identification in Russian Sturgeon

Developing early molecular sex-determination tools for Acipenser gueldenstaedtii to optimize caviar production in Israeli aquaculture farms.

🔬

Epitranscriptomic Regulation (m6A) in Fish & Amphibians

Characterizing m6A RNA methylation variation across life stages and sexes in Ommatotriton vittatus and Blue Gourami using high-throughput sequencing.

🦎

Ecology of Salamandra infraimmaculata in Northern Israel

Long-term field study of breeding site ecology, population dynamics, and habitat threats at Sasa pools, Zavitan Stream, and Dan Stream sites.

🪸

Coral Aquaculture Production Systems

Investigating controlled coral cultivation methods for reef restoration and the commercial potential of coral-based aquaculture in Israel.
