Dr. Arti Choudhary’s research is focused on on-road emission characterization and emission modelling. She is currently working at the Central Road Research Institute (CSIR-CRRI). She has a PhD from the Department of Civil Engineering, Indian Institute of Technology Guwahati (India) and M.Tech. from Thapar University, Patiala (India).
Her past research was funded by the Ministry of Human Resource Development (MHRD), Government of India and recently, she was awarded the SERB-National Postdoctoral Fellowship by the Department of Science and Technology, Government of India.
A short Q & A with Dr. Choudhary:
What is your SERB project focused on?
My SERB project focused on three different engine type auto-rickshaw, like petrol fuelled auto-rickshaw, CNG fuelled auto-rickshaw and e-rickshaw, for on-road driving cycle development and on-road emission factor (EF) estimation for two different cities- Delhi and Guwahati. Some other focus points of the project are assessment of operational and financial performance of e-rickshaws and CNG fuelled auto-rickshaws as compared to petrol-fuelled auto-rickshaws in terms of emission reduction potential per kilometre, fuel economy, maintenance cost per kilometre, operating costs per passenger, and the ratio of operating costs to traffic revenues.
How did you get interested in the field of air pollution?
The topic of air pollution and its impact on the environment is important and is highly relevant in the wake of the alarming air pollution in the most of the urban cities of India. I found my interest in air pollution during my M.Tech. dissertation project. Through sampling and analysing (size-segregated) PM across locations, I learnt about the dynamic behaviour of pollutants, seasonal variation and its impacts on human health and our environment. I found real time data collection, analysis and assessment of its impact in real world to be very interesting. This motivated me to continue research on air pollution and during my PhD, I chose to study transportation sector for real-world emission characterization, which is one of the significant sources of air pollution, particularly in urban areas.
As a young scientist, what are the biggest challenges you face in terms of conducting research?
As a researcher, I found instrumentation to be the biggest challenge in air pollution research in India. Collaborative research across the nation is neither flexible nor supportive. For quality research, we need to manage better collaboration across national and regional research laboratories and scientific organizations, and better linkages with the foreign academic community.
