my coordinates:

Here in google maps at the encircled black and white point you find my office at the first floor. Parking is possible at the parking lots P11 and P14 visible at the upper edge of the map. Acces to the office building is from Allée du Six Août.

major research topics:

  • solvent and reactive extraction: develop and validate a design tool for extraction columns based on the drop-based simulation of the columns, where the parameters of the drop models are determined from lab experiments
  • coalescence, liquid-liquid phase separation, and settlers: settler design based on single-drop modelling, where the coalescence parameters are determined from a lab-scale settling experiment
  • exergetic evaluation and advanced thermodynamic modelling: exergo-economic comparison of entire process routes and individual process steps is performed, especially for bio-based substances advanced thermodynamic models are derived
  • sustainability, specifically application of balances to characterize scenarios of global future development.
