About me

The central aim of my studies is to understand the chemical transformations and environmental impacts of atmospheric pollutants, including aerosol nanoparticles and mercury. Research into these topics is not only attractive from a fundamental scientific standpoint but also helps to develop the appropriate control measures to reduce environmental pollution.

RESEARCH & INDEP STUDY I

Cycling of Atmospheric Mercury

The goal of this project is to understand the chemical speciation of atmospheric oxidized mercury and elucidate the role of gas-phase and surface reactions in the cycling of mercury between elemental and oxidized states

Background

Mercury is a persistent, bioaccumulative pollutant. A large fraction of atmospheric mercury is emitted in elemental form (Hg0) by coal-fired power plants. Oxidation of Hg0 followed by atmospheric deposition is the primary cause of mercury contamination of the aquatic environment. Current knowledge of the chemical processes that cycle mercury between elemental and oxidized states is highly uncertain.

Approaches

  • Experimental studies of mercury oxidation and reduction
  • Development of highly sensitive mass spectrometry instrumentation for speciation of atmospheric oxidized mercury
  • Field measurements of atmospheric oxidized mercury.

Expected outcomes

Resolve an ongoing debate about the relative importance of different mercury transformation pathways in the atmosphere. Update mercury chemical mechanisms in mercury transport and deposition models. Better understanding of mercury methylation and bioaccumulation.

Transformations and Impacts of Atmospheric Aerosols

This project aims to understand the chemical and physical mechanisms responsible for the transformation of atmospheric aerosols as well as associated impacts of aerosols on climate and human health.

Background

Atmospheric aerosols originate from two major sources: direct particle emissions and gas-to-particle conversion of low- and semi-volatile species from atmospheric gas-phase oxidation. Increased aerosol loading of the atmosphere has negative impacts on air quality and human health and contributes to local and global climate change. Presently, the chemical and physical mechanisms responsible for the transformation of aerosol particles are not well understood. Impacts of aerosols on the environment and human health are poorly quantified, as well.

Approaches

  • Experimental studies of gas-surface interactions involving organic and combustion soot aerosols
  • Characterization of  radiative and cloud forming properties of aerosols
  • Development of hyphenated mass spectrometry instrumentation for analysis of aerosol nanoparticles
  • Field measurements of atmospheric aerosols.

Expected outcomes

Improve representation of aerosol direct and indirect radiative forcing in atmospheric models to reduce uncertainties in climate prediction. Better understand aerosol health impacts to develop control measures to reduce environmental pollution.
