Research Scientist, PhD

Plant cell wall and polymers (PVPP)

Richard Sibout-2018-10-01

Richard Sibout obtained a PhD in Forest Biology from Université Laval (Canada) under the scientific direction of Dr. Armand Séguin and Prof. John Mackay in 2005. After a short stay at McGill University in Montreal, he did a postdoctoral fellowship at the University of Lausanne in Switzerland in the team of Prof. Christian Hardtke.  In 2011, he took over the leadership of the research team “Paroi secondaire” until then led by Lise Jouanin on the INRA Centre in Versailles.
 
Since February 2018, Richard Sibout has been a research fellow in the PVPP team of the BIA Unit in Nantes. As a biologist specialized in Brachypodium genomics (a model plant for grasses) and in the comprehension of plant cell wall formation, particularly the lignification mechanisms, he is currently studying the parameters inherent in ligno-cellulosic biomass that control the deconstruction of plant cell walls. 
 

Fields of practice:

  • Biochemistry of plant walls
  • Genomics of grasses
