Dr. Sachchida Nand Tripathi is a Higher Administrative Grade (Senior) Professor of Civil Engineering at IIT Kanpur and joint faculty at the department of Sustainable Energy Department (SEE), IIT Kanpur. He is the recipient of Shanti Swarup Bhatnagar Award and the J C Bose National Fellowship. Prof. Tripathi holds the Arjun Dev Joneja Chair at IIT Kanpur. He is an elected fellow of the Indian National Science Academy (INSA), Indian National Academy of Engineering (INAE) and National Academy of Sciences of India (NASI) and recipient of the Distinguished Alumnus award of Banaras Hindu University. He was a Senior Fellow at NASA Goddard Space Flight Centre. He has made impactful contribution to address challenges of Air Pollution and Climate Change. Prof Tripathi has built ground-breaking innovative approaches for indigenously built low-cost sensor-based network technologies for nation-wide urban air quality monitoring and Real Time Source Apportionment (RTSA). His work on Taj Mahal discolouration led to policy interventions in Agra city. His pioneering work in aerosol-induced cloud invigoration effect (AIvE) and synergy of coupling between urban land use, land cover and Cloud Condensation Nuclei-induced AIvE has contributed significantly in future urban planning to avoid flash floods.

He is also the Coordinator of the National Knowledge Network, formed under the National Clean Air Program and an expert member of Steering Committee and Monitoring Committee, National Clean Air Program and member of Executive Council, Climate Change Program, Department of Science and Technology.

Prof. Tripathi’s new study discovers the genesis of night-time air pollution. It provides mechanistic understanding of nanoparticles growth preceding severe haze pollution in Delhi, which is due to biomass burning emissions.
