Sally Ng is one of the top experts in the world on aerosol science – the study of tiny particles in our atmosphere – and what they mean for our climate and our health. Ng is an associate professor in the School of Earth and Atmospheric Sciences and the School of Chemical and Biomolecular Engineering. She describes her work testing air quality in the field and in a special indoor lab that she designed in this week's ScienceMatters Season 3 Episode 5.
Ng has put a game-changing research spotlight back on trees, which play such an important role in the planet’s air quality. That’s also why she’s spending more time than ever wondering about what happens to our atmosphere when a lot of those trees are reduced to ashes during wildfires, which are growing in frequency and intensity.
Since joining Georgia Tech in 2011, Ng has built a formidable research team trying to answer those questions. She has already added considerable insight into what aerosols can do to the environment, winning awards and grants in the process. Ng's published work has been cited more than 10,000 times.
Each ScienceMatters episode includes a quiz that refers to facts mentioned in each podcast. A winner will be chosen randomly from all who submit correct answers. Winners will receive special College of Sciences gifts.
The Episode 5 quiz question:
How many ultraviolet (UV) lights are in the special indoor environmental chamber that Sally Ng designed?
The winner will be announced in the following week.
