About me

I am a PhD student at the Université Libre de Bruxelles (ULB) since October 2015.

The main aim of my PhD project is to evaluate the significance of several biological characteristics that may modulate calcification sensitivity of metazoans in the context of ocean acidification. The study is based on a comparative approach in postmemorphic echinoderms – principally star fish and sea urchins – with different diet, contrasted acid-base regulation capacity and originate from diverse habitats. Concretely, I focus on biomechanical characteristics of the calcified skeleton of several species subject to long term ocean acidification experiment.

I did my bachelor in biology and my master in biology of organisms and ecology at ULB. My master thesis was also conducted at the Marine Biology lab of ULB and was about the physiology of Paracentrotus lividus and Arbacia lixula in the context of ocean acidification experiment.

Projects

  • Morphology and biomechanics of skeleton of postmetamorphic echinoderms
  • Genetic expression of proteins linked with calcification
  • Comparison of morphological, mechanical, genetic data and biological (ecological) characteristics

Position

PhD student (FRIA grant)
