Meet leading researchers and experts in plants, green walls and air quality.


We are the UTS Plants and Environmental Quality Research Group led by Dr Fraser Torpy and Dr Peter Irga. We are one of the world’s leading air phytoremediation groups and our primary focus is on empirical, industry-linked research to develop plant-based systems to mitigate poor urban air quality. Our research explores the relationship between plants and air quality through laboratory based studies, indoor and outdoor sampling, and city-scale geospatial analyses.
