Thibaut de Bettignies (postdoc 2013-2015)

Tib landed a job a Chargé d’étude at the Muséum National d’Histoire Naturelle in Paris and returned to France.

Research summary

I am currently a postdoc in the Wernberglab in the School of Plant Biology, based within the UWA’s Oceans Institute. My responsibilities include assisting in the every-day running of the lab, supervision of students, and research in the following areas:

  • Seaweed phenology (patterns and shifts in fecundity and productivity)
  • Biomechanics of kelp and the prediction of physical disturbances
  • Eco-physiology of temperate seaweeds and response to climate forcing
  • Evaluation of kelp ecological performance (productivity, recruitment, fecundity)
  • Reef community dynamics & tropicalisation of temperate reefs (e.g. high latitude corals)
