Ajit is a Postdoctoral Research Fellow in the group of Professor Francis Pope. Currently, he is working on ASAP East Africa project (www.asap-eastafrica.com), which aims to conduct a quantitative study of urbanisation trends and their impact on air quality, while generating a holistic evidence base on the causes, consequences and levels of air pollution. The project also identifies social, environmental, policy and management measures to tackle air pollution, through a series of field observations, laboratory experiments, combining online measurements with state-of-the-science offline analyses. 

Previously, he has worked with Professor Roy Harrison's group under FASTER project, where his Postdoctoral research was focused on understanding sources, properties and environmental behavior of exhaust nanoparticle from roadside vehicles.
