Ajit Singh is a postdoctoral Research Fellow in the group of Professor Roy Harrison. Currently, he is working on FASTER project, where his research focus on understanding sources, properties and environmental behavior of exhaust nanoparticle from roadside vehicles. The research involves both laboratory and field measurements.

  • 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.
