This research investigates the formation and chemical composition of atmospheric aerosol particles, particularly secondary organic aerosols formed through oxidation of organic gases. Using a large controlled atmospheric chamber, the work studies how environmental conditions influence aerosol chemistry, improving understanding of air pollution, climate impacts, cloud formation, and human health effects.

This research investigates how microplastics and nanoplastics affect human cells. Using laboratory models that mimic the digestive system, it examines how particle size and concentration influence toxicity. The findings show that smaller particles are more harmful, providing evidence that can inform safety regulations and reduce human exposure to plastic pollution.
