Topics that I work on or plan to work in the future include studies
of: + missing
aerosol species and sources, such as the primary oceanic
aerosols and their importance on the remote marine atmosphere, the in - cloud and
aerosol water aqueous formation
of organic
aerosols that can lead to brown carbon formation, the primary terrestrial biological
particles, and the organic nitrogen + missing
aerosol parameterizations, such as the effect
of aerosol mixing on cloud condensation nuclei and
aerosol absorption, the semi-volatility
of primary organic
aerosols, the importance
of in - canopy processes on natural terrestrial
aerosol and
aerosol precursor sources, and the mineral dust iron solubility and bioavailability + the change
of aerosol burden and its spatiotemporal
distribution, especially with regard to its role and importance on gas - phase chemistry via photolysis rates changes and heterogeneous reactions in the atmosphere, as well as their effect on key gas - phase species like ozone + the physical and optical properties
of aerosols, which affect
aerosol transport, lifetime, and light scattering and absorption, with the latter being very sensitive to the vertical

aerosols +
aerosol - cloud interactions, which include cloud activation, the
aerosol indirect effect and the impact
