Carrier at IRD

  • Recruitment in 1989 as second class researcher (CR2)
  • Posted in Yaoundé, Cameroon from 1990 to 1996
  • Promoted as first class researcher (CR1) in 1994
  • Posted in Bondy, France (IRD Research Center) from 1996 to 2009. Numerous missions in foreign countries (Burkina Faso, Madagascar, Benin, India, Lao PDR, Thailand)
  • Posted in Bangkok, Thailand (Land Development Department) from 2009 to 2014
  • Posted in Bondy, France (IRD Research Center) since 2014.

Main research activities

  • Integration of different surface geophysics methods (Electrical Resisitivty Tomography, EM31, TDEM) for the study of the layering and the water fluxes within tropical soil covers (Cameroon, Burkina Faso, Benin, Madagascar, India, Lao PDR, Thailand, France)
  • Laboratory experiments aiming at establishing equations linking electrical resistivity with the water content of soils taking into account the shrinkage of porosity during desiccation.
  • Development of interpretation tools for geophysical measurements (Filtering of apparent resisitivty data before inversion, Bayesian inversion of « 3 points vertical electrical soundings »).
  • Study of soil-climate-plant relations in unconventional agricultural lands in South-East Asia (fallow-cultivation successions on slopping lands in Lao PDR, rubber tree plantation on sandy or hydromorphic soils in Thailand)
