Research Description

This laboratory's research is at the intersection of analytical and physical chemistry. Our laboratory's mission is to explore significant fundamental and applied research questions on physicochemical processes involving particles (in air, aka aerosols) and organic and metal pollutants of relevance to the Earth's atmosphere and its interfaces (air-snow/ice/water/soil). We also develop novel sustainable technology (natural nanoparticles, energy-neutral, and recyclable) for air and water pollution remediation, & cutting-edge technology and methods for ultra-trace detection of gaseous and particulate matter. Our direct research contributions include the following:

  • Physical and analytical chemistry.
  • Climate change.
  • Sustainable chemistry and technology.
  • Air pollution.
  • Nano-science.
  • Environmental health and medicine.


Our current active research R&D themes in our laboratories are that are performed by field observation, laboratory experiments, numerical modelling and sustainable technologies (sensors and Zero-net energy for pollution remediation):


  1. Development of novel four-dimensional technologies for particles and advancing physicochemical properties of airborne Nanoparticles (single and cluster particles) in the atmosphere and air/snow/water interfaces
  2. Ice nucleation microphysics: Interactions of aerosol-cloud interactions
  3. Urban & Arctic air pollution: Impacts on human and ecosystem health
  4. Emerging contaminants: Nano/microplastics, electronic waste, rare metals, nanometals etc., in air/water/ice,
  5. Development of sustainable technology Natural material, recyclable, energy neutral, and efficient, with detailed studies of life cycle analysis
  6. Bioaerosols: We develop new technologies for single virus observation in dynamic and stationary modes. We also perform experiments on RNA/DNA and genomic of airborne particles, as well as those in air/water/snow
