Research

free hit countersExtensive work in the Guzman Lab focuses in the study of the interaction of light with organic compounds present in low water activity environments such as atmospheric aerosols, clouds, and fogs. Mechanistic studies explore reactions of dissolved organic matter within aqueous aerosol mimics. The laboratory applies soft ionization methods coupled to mass spectrometry to explore the fast oxidation of halides and phenols at the air-water interface. Because past work has focused on the study of reactions in ice matrices, the laboratory is also experienced in ice chemistry. We are also interested on the potential use of photocatalysis for fuel production and to jumpstart a prebiotic chemical cycle related to the origin of life. In general we are interested in studying processes occurring in environmental interfaces and in research problems of interdisciplinary scope.
