Biographical Info

Research Areas

  • Development of aerosol/bioaerosol sampling, control, and generation methods
  • Investigation of aerosol and bioaerosol monitors’ performance
  • Integration of bioaerosol sampling tools with advanced microbiological analysis techniques Aerosol exposure assessment
    Indoor air quality
  • Exposure and health effects of nanoparticles

Research Highlights

  • Investigated the potential release of particles from nanotechnology-based consumer products and showed that their use could result in inhalation exposures to nanoparticles and their agglomerates
  • Developed a novel electrostatics-based collector for biological aerosols where airborne particles could be captured into very small amounts of liquid (5-40 microliters) thus allowing to measure low concentrations of airborne microorganisms.
  • Investigated indoor exposures of young children to airborne contaminants using a novel robotic sampling platform. The research shows that the current exposure assessment methods using stationary samplers may underestimate exposures by a factor of 3.

Scholarly Activities

  • Co-Chair of the “Health-Related Aerosol Working Group” of the American Association for Aerosol Research for 2010-2011.
  • Member, Aerosol Technology Committee, American Industrial Hygiene Association.
  • Member, Stakeholders’ Panel on Agent Detection Assays (SPADA), organized by AOAC International, contracted by the Department of Homeland Security’s Chemical/Biological Research and Development Section (CBRDS)
  • Reviewer for scholarly journals
