Research interests
Our laboratory's mission is to explore major fundamental, and applied research questions on chemical and physical processes involving aerosols, as well as organic and metal pollutants of relevance to the Earth's atmosphere and its interfaces. Our direct research contributions are to the fields of Atmospheric sciences and climate change, specifically aerosol-cloud interaction, air pollution, atmosphere-ocean interactions, physical and analytical chemistry, sustainable chemistry and technology, nanoscience, environmental health and medicine.
The IPCC (2013) points to the importance of aerosol-cloud processes due to their impact on the absorption and scattering of radiation, altering the Earth's climate, where as the WHO (2015) predominantly considers aerosols as to be health hazards. It has become increasingly clear that both the climate and toxicity-health impact of nanoparticles are significantly affected by physical and chemical processes such as size, gas-particle partitioning, hygroscopicity, liquid-liquid phase separation, redox kinetics, surface tension, viscosity, molecular configuration, active sites, surface properties, and chemical composition. We have established expertise and infrastructure to perform aerosol research, including nanoparticles in air and air/snow/water surfaces, by contributing to address key uncertainties described above, and pioneering novel questions and solutions, with which affect climate and health challenges.
Our research are performed through complementary field (from Arctic to urban), laboratory and modeling research. Our state-of-the-art kinetic, surface and photochemical laboratory investigations are performed using ultra-fast and sensitive detection using various high resolution lasers, second harmonic generation, long path FTIR, FT-Raman, various mass spectrometry, microscopy, surface sciences, air pollution and aerosols analyzers. We develop techniques and perform highly sensitivity measurements of trace gaseous and particulate compounds. Complementary computational and atmospheric chemical modelling of the reaction intermediates in the atmosphere to simulate the complex physical-bio-chemical interactions. During the last decade, we develop novel sustainable technology in air and water pollution remediation and smart sensors, which are efficient, energy neutral, recyclable with no waste, and their life cycle analysis have been considered prior to their design and development.
Our active research themes in our laboratories are:
- Aerosol-cloud interactions: Microphysics, ultra-trace characterization, ice nucleation
- Metals (namely Hg) in atmosphere and air/snow/water interface.
- Bioaerosols: Impact on Chemistry and Physics of the atmosphere.
- Development novel techniques for sustainable technology: Natural material, recyclable, energy neutral, efficient, with detailed studies of life cycle analysis
- Nanoparticles in atmosphere and in air/snow/water interfaces
- Urban & Arctic air pollution
