Research area

My research is focusing on:

  • Research, development and design of physical and chemical processes for water, wastewater and solid waste treatment.
  • Research on processes to identify factors that limit mass transfer, kinetics, equilibrium and phase separation by means of natural clay minerals (clinoptilolite and mordenite).
  • Environmental quality (water, soil and biota) monitoring.
  • Water and solid waste treatment by physical-chemical and biological method  (bioremediation techniques).
  • Environmental Policy
