Maddie Camp's research interests include formation of secondary pollutants, emmission fate and transport and the relationship between emissions and climate change. This summer at CMMAP, she worked with Dr. Sonia Kreidenweis looking at a new way to measure irregular particles.

Aerosols impact cloud reflectivity and cloud residence time by acting as cloud condensation nuclei (CCN). Traditional lab methods for measuring properties dictating CCN activity are unable to accurately measure particles with non-spherical geometry such as iodine oxides. Maddie applied a novel wet CCN measurement method that collapses fractal iodine oxide particles to provide an accurate measurement of water uptake and CCN activity of irregular particles.

Fractal iodine oxide particles form through oxidation of molecular iodine and other iodic compounds released in coastal regions by algae. Subsequent condensation forms small nuclei that agglomerate into larger irregular particles. Maddie's research poster, Cloud Nucleating Activity of Non-Spherical Particles: Application of Wet CCN Measurement to Iodine Oxides, may be found here.

Maddie's hometown is Vancouver, WA. She attends Rice University and will be a junior in the fall. Her major is civil and environmental engineering. Outside of school, she likes to hike, bake, sew and also enjoys bird watching.
