Introducing IOLR’s new scientists

In the 49 years since IOLR’s founding in 1967, many distinguished marine scientists have worked in our labs, aboard our ships, and in the field as IOLR faculty.

Because science is always changing, recruiting the best young scientists is critical for a scientific institution to stay current. These new recruits bring their recent training and new ideas, rejuvenating the institution.

IOLR is proud to have recruited these outstanding young scientists to its faculty since 2013. Here is an introduction to IOLR – The Next Generation.


Dr. Timor Katz

Timor Katz

Ph.D. 2010, Hebrew Univ.

IOLR since 2014

NIO, Marine Geology

Research interests:

Marine sedimentological processes including sediment fluxes, transport, accumulation and geochemical interactions with the water column. Current studies explore the effects of biological resuspension in the marine environment, introduction of terrestrial sediments into the Gulf of Aqaba in desert flash floods and their progress underwater as hyperpycnal plumes, post deposition dispersal of flood sediments and the effects of a multitude of environmental variables on sediment fluxes and composition along the Mediterranean Sea.

Dr. Eyal Rahav

Eyal Rahav

Ph.D. 2013, Bar Ilan Univ.

IOLR since 2013 

NIO, Marine Biology

Research interests:

Studies on biological oceanography with an emphasis on the factors that control phytoplankton and bacteria biomass, diversity, physiological status, bacterial and primary productivity and dinitrogen fixation rates in varying aquatic ecosystems. 

Dr. Peleg Astrahan

Peleg Astrahan

Ph.D. 2010, Hebrew University

IOLR since 2013 

KLL, Organic Chemistry

Research interests:

Marine and freshwater organic matter chemistry. Among the studied topics are the type, distribution and fate of molecules such as polysaccharides, dissolved organic nitrogen, oil degradation products and pesticides. In addition to these topics, I study the unique ecosystem of the microlayer which is the contact layer between the water and the atmosphere.

Dr. Shira Ninio

Shira Ninio

Ph.D. 2004, Hebrew University

At IOLR since 2015

KLL, Microbiology

Research interests:

Marine microbiology, bacterial biofilm formation, microbial pathogens in the environment, Legionella pneumophila, bacteria-protozoa relationships, molecular techniques for monitoring microorganisms in aquatic systems. 

Dr. Yaron Be’eri Shlevin

Yaron Beeri Shlevin

Ph.D. 2008, Ben-Gurion University

IOLR since 2014

KLL, Geochemistry

Research interests:

Water geochemistry with a focus on trace element geochemistry, lake and oceanic sediments, salinity issues in Lake Kinneret, geochemistry of the Southern Jordan River.

Dr. Amir Bitan

Amir Bitan

Ph.D. 2012, Ben- Gurion University

IOLR since 2013 

NCM, Marine Biology

Research interests:

Stock enhancement by nutritional programming and Epigenetic manipulations on fish embryos and larvae using Zebrafish and Seabream as model species.

Appetite mechanisms and peptide absorption in farmed fish (e.g seabream, sea bass, grey mullet, grouper and bluefin tuna).

Identification of nutritional requirements of fish and shellfish and development of practical feed formulations to optimize their growth.

Dr. Lior Guttman

Lior Guttman

Ph.D. 2012, Hebrew University

IOLR since 2013 

NCM, Microbiology

Research interests:

Innovative agro-technologies for biofiltration of mariculture effluents using bacteria and other marine microorganisms.

The study of microbial and microorganism biodiversity and activity in complex environments (e.g. fish gut, biofilters/bioreactors, food chain, etc.) using advanced metagenomic sequencing.

The potential of microorganism-based diet (Periphyton, bioflocks) as food source for marine fish and shellfish and its impact on culture health, performance and nutritional economy.

Dr. Galit Sharon

Galit Sharon

D.V.M., Ben- Gurion University

IOLR since 2015 

NCM, Marine Biology

Research interests:

Fish health, immunology, pathology, and parasitology.

Prevention and treatment of fish diseases.

Fish nutrition in aquaculture.

Proper care and use of aquatic animals in research.
