Summary:

I taught core courses in chemistry, environmental and chemical engineering in several universities. I have a long industrial experience as a process engineer working in a large petrochemical plant and a fertilizer’s complex. I did consultation to many companies in the chemical, petroleum, energy, hydrometallurgy and environmental fields. I led groups doing research in the field of air, water, soil pollution and treatment, energy, catalysis and rare metal extraction in several research institutes. I was a member of IPCC/TFB for 12 years working on emissions of GHG.
