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. 

Qualifications

  • PhD  –  School of Geography, Earth and Environmental Sciences, University of Birmingham, UK
  • M.Tech. – Indian Institute of Technology (IIT), Delhi, India
  • B.Tech.

Biography

Ajit Singh obtained his PhD degree in Environmental Sciences from University of Birmingham and M.Tech. Degree from Indian Institute of Technology (IIT), Delhi in the field of Atmospheric Sciences. His PhD research included the investigation of the combined influence of aerosols and meteorology on visibility and tropospheric chemistry. He developed a light extinction model incorporating the concentration and composition of historical data to explain the visibility trend. He also investigated HONO (Nitrous acid) variations and their control by meteorological, long range pollution and traffic emission factors. His Master’s Thesis was focused on visibility-aerosol relationship, where he employed OPAC model to identify the influence of different aerosol type on visibility change. He is currently working as a Research Fellow continuing his interest in the measurement of atmospheric particle.
