Having followed a multidisciplinary path, I decided to specialise in the field of chemical ecology. I began my PhD in November 2024 with the aim of studying emissions of biogenic volatile organic compounds (bVOCs) from the litter of urban plant species and understanding their impacts on air quality in the context of climate change. This PhD research is divided into three stages:

  • Understanding the answer (ex situ) VOC emissions from the litter of six species (Celtis australis, Cercis siliquastrum, Ficus carica, Liquidambar styraciflua, Pinus halepensis and Sophora japonica) at the temperature
  • To characterise VOC emissions from P. halepensis during a daily cycle (in-situ, at the St Jérôme Botanical Gardens – MARSEILLE)
  • To assess the impact of heating and decomposition on VOC emissions from P. halepensis (following the study carried out by Viros et al., 2020)
  • 2024-2027 – PhD student – IMBE; Aix-Marseille University
  • Licence (CMI) - Earth Sciences - University of Poitiers
  • Masters (CMI) - Environmental Sciences - Coastal Geosciences and Geophysics, EGEMM option - University of La Rochelle
  • Chemical ecology
  • Analysis of soil microorganisms (PLFA)
  • Biogenic volatile organic compounds

My PhD thesis is entitled “Litter from tree species in urban environments under different climate scenarios: implications for air quality and the importance of biotic and abiotic drivers”, which I am undertaking under the supervision of Elena Ormeño Lafuente (IMBE), Mathieu Santonja (IMBE), Julien Kammer (LCE) and Henri Wortham (LCE).
