Welcome to the Zondlo group website!
My research group studies fundamental areas in the atmospheric sciences such as cloud formation, the composition of aerosol particles in air quality, and the sources of greenhouse gases. The effects of aerosol particles and cloud formation on climate are the largest sources of uncertainty in predicting anthropogenic activities on climate.
To research these areas, my group develops novel optical sensors and deploys them in field campaigns in ground-based networks and on aircraft-based research platforms. As part of the NSF Center for Mid-Infrared Technologies for Health and the Environment (MIRTHE), we apply new advances in state-of-the-art quantum cascade lasers and vertical cavity surface emitting lasers to problems of atmospheric importance. These new light sources allow for unprecedented capabilities to probe the atmosphere, thereby advancing the understanding of societal problems of air quality, global climate change, and ozone depletion.
