Through her graduate and post-graduate studies Sarah has been very actively involved in research on atmospheric aerosols. Aerosols are small particles suspended in the atmosphere that interact with sunlight, thereby reducing the amount of sunlight that reaches the surface of the earth and, when the particles are dark (i.e. gray, brown or black), heating the atmosphere. These particles can also affect climate by interacting with clouds, changing their reflectivity, likelihood of precipitating, and how long the clouds last. Sarah’s research has mostly focused on field measurements of aerosols and associated instrument work. She holds a patent on a specialized instrument she developed to measure aerosol optical properties as part of her PhD work. In addition to direct research, she has a strong interest in science management. For seven years (2003-2010) Sarah was the Executive Officer of the International Global Atmospheric Chemistry Project where she combined her research efforts with organizing multi-national science initiatives, workshops and conferences.
