My research specialty is the reproductive physiology of fish. I am currently investigating the molecular mechanisms of reproductive function and determination of egg quality. These studies presently target  Atlantic halibut (Hipoglossus hippoglossus) and another marine species, the European plaice (Pleuronectes platessa). Special emphasis is placed on the contributions of multiple yolk precursor proteins, vitellogenins, to developmental competence. I use a variety of high throughput, leading-edge molecular biology and proteomics methodologies to investigate the causes of reproductive disorders and consequentially discover practical solutions that can lead to improvements in mass production of established and emerging aquaculture species.  


I obtained my B.Sc. and first M.Sc. in Fisheries Engineering emphasizing Aquaculture from Cukurova University (Turkey), after completing my research at the Hellenic Centre for Marine Research (Greece) under the supervision of Dr. Constantinos Mylonas, in 2004. I obtained my second M.Sc. degree in Aquaculture emphasizing Fish Reproductive Physiology after completing my research under the supervision of Dr. Silvia Zanuy at the Instituto de Acuicultura de Torre la Sal (Spain), in 2006. During this period my research focus was on reproductive system development, maturity and gamete quality in male fish. I completed my Ph.D. studies on molecular characterization of the multiple vitellogenin system in European sea bass in collaboration with Dr. Francisco Prat at the Instituto de Ciencias Marinas de Andalucia (Spain) and with Prof. Craig V. Sullivan at North Carolina State University (USA), obtaining my Ph.D. degree from Akdeniz University (Turkey) under the supervision of Dr. Sadi Koksoy in 2013.  My first postdoctoral research explored the contribution of multiple vitellogenins to gamete quality in zebrafish using novel technologies in genome engineering, proteomics and molecular biology. This work was conducted in collaboration with Dr. Julien Bobe at the French National Institute for Agricultural Research until 2017. During my  second postdoctoral experience in the Department of Biology at the University of Bergen, together with Dr. Nigel Finn I investigated structure-function relationships in molecular (water/glycerol/urea) channels, termed aquaglyceroporins, of Atlantic salmon (Salmo salar) and of the salmon louse (Lepeophtheirus salmonis). This work involved close collaboration with Dr. Joan Cerda at the Institute of Agrifood Research and Technology (IRTA) in Barcelona. Several prestigious international awards have supported my career development detailed above including, as examples, a Fulbright Research Fellowship and an EC-Marie Curie Intra-European Fellowship for Career Development. I significantly contribute to my field of research through regular publications in esteemed international journals and via presentations at important international meetings. As evidenced above, my research network includes collaborators from all over Europe, the USA and Japan. I speak Turkish, English, Spanish, French and I have been improving my Norwegian skills since October 2018, when I joined the IMR.
