Guillaume Marcotte, Ph.D.

Junior scientist - Dispersion modelling source term and chemical accident specialist

CURRENT S&T / RESEARCH - I am developing sofware solutions for the estimation of source terms in atmospheric modelling and fate and behaviour modules in oil spill dispersion.

  • Atmospheric dispersion
  • Fire modelling - smoke, heat, plume and gases
  • Aquatic dispersion of oil products
  • Fate, behaviour and weathering of oil products
  • Ice - oil interaction


  • Atmospheric chemistry
  • Water chemistry
  • Pollution
  • Environmental emergencies
