My research focus is to underpin the impacts of environmental changes on cellular physiology and processes of toxic cyanobacteria with the aim of better understanding population and community dynamics


Savannah is a PhD researcher at the Aquatic Ecology department of NIOO-KNAW. She graduated with a Bachelor in Chemical Engineering in 2016 from the American University of Beirut, and a Master in Freshwater and Marine Biology from the University of Amsterdam in 2022. Her research interests include ecological stoichiometry and the impact of nutrient ratios in the environment on cellular functioning and responses. Specifically, in her PhD she is focusing on carbon, nitrogen and phosphorus impacts on the toxicity of freshwater cyanobacteria.

  • Climate change impacts on harmful algal blooms

    Project 2022–Present
    Harmful cyanobacterial blooms produce toxins that are a major threat to water quality and human health. Blooms increase with eutrophication and are expected to be amplified by climate change. Yet, we lack a mechanistic understanding on the toxicity of blooms, and their response to the complex interplay of multiple global change factors. Bloom toxicity is determined by a combination of mechanisms acting at different ecological scales, ranging from cyanobacterial biomass accumulation in the ecosystem, to the dominance of toxic species in the community, contribution of toxic genotypes in the population, and the amounts of toxins in cells.
