Research Interests are in the chemical, physical and optical properties of atmospheric aerosols; impact of aerosols on climate; size-resolved chemical composition and sources of aerosols in tropical regions; carbonaceous aerosols; organic aerosols and their role in cloud condensation nuclei properties; impact of atmospheric aerosols on the ecosystem, the degradation of structures and health.
