Biography
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.
