Research interests:

I am interested in the development of ecosystem models and their application as both a research and management tool for freshwater and marine ecosystems. This includes examining the impact of processes on the ecosystems by using long-term scenario simulations, the study of the factors affecting the ecosystem, and the potential changes that may occur as a result of changes to management measures of environmental conditions. I study possible ways for enhancing model testing tools and use a variety of models including DYRESM-CAEDYM, GLM-FABM, Ecopath with Ecosim and Ecospace and data-driven models. My interests also include the study of food-web trophic interactions especially at zooplankton-phytoplankton and zooplankton-fish levels. I am in charge of the zooplankton monitoring of Lake Kinneret and study the long term changes to the zooplankton population as a result of environmental changes and management approaches.
