Arbeidsområde

My research lies within the field of zooplankton and larval fish taxonomy and ecology. The study of key environmental factors governing mesozooplankton and fish larvae community structure has been one of my major research lines. My expertise in taxonomy and biological-physical coupling were initially developed through my research in the Mediterranean ecosystems using traditional taxonomic criteria. From 2015-2018, my research was extended to the Red Sea environment and incorporated the application of molecular techniques for species identification and biodiversity assessment.

I have additionally developed a parallel multi-year engagement in zooplankton eco-physiological studies, aiming to better understand the organismal responses to environmental parameters/stressors, the “bottom up” processes and overall trophic interactions in the planktonic food web. I have explored interactions between different trophic levels (phytoplankton, microzooplankton, mesozooplankton) aiming to gain a broad and in-depth understanding of the structure and function of marine planktonic environments. 

Currently, I am the IMR focal point for the Plankton research in the EAF-NANSEN project (Supporting the application of the Ecosystem Approach to Fisheries management considering climate and pollution impacts).
