Research Interests

  • Instrumental development for measuring semivolatile organic compounds in the gas and the aerosol phase.
  • Developing new instrumental techniques for measuring atmospheric trace gases (e.g., halocarbon, reduced sulfur gases and alkyl nitrate).
  • Flux measurements of atmospheric trace gases at different ecosystems.
  • Estimation of short lived free radical concentration (e.g., NO3, OH)
  • Atmospheric modeling

Education
