Institute Professor, department of Earth, Atmospheric and Planetary Sciences and Department of Chemistry,Massachusetts Institute of Technology, USA.
Professor Mario Molina has been involved in developing our understanding of the chemistry of the stratospheric ozone layer and its susceptibility to human-made perturbations. In 1974 he was a co-author, with F. S. Rowland, of the publication in the British magazine Nature, of their research on the threat to the ozone layer from chlorofluorocarbon (CFC) gases that were being used as propellants in spray cans, as refrigerants, as solvents, etc. More recently, he has also been involved with the chemistry of air pollution of the lower atmosphere. He is also pursuing interdisciplinary work on tropospheric pollution issues, working with colleagues from many other disciplines on the problem of rapidly growing cities with severe air pollution problems.
