Biography

Prof Kumar is a founding Co-Director of the pan-university Institute for Sustainability, Professor and Chair in Air Quality and Health, and founding Director of the internationally-leading research centre Global Centre for Clean Air Research () at the ºÚÁÏÉç, UK. He is the founder of successfully running Guildford Living Lab, a Trustee at , an Adjunct Professor at Trinity College Dublin, Ireland; and a Guest Professor at Southeast University, China.

He joined the Senior Leadership team of the Faculty of Engineering and Physical Sciences as an Associate Dean (International) in 2020 and subsequently took up another senior leadership role to help setup the new pan-University Institute for Sustainability as a founding Co-Director in 2023. As an Associate Dean (International), he worked on implementing the University's Global Strategy and provided leadership to the international agenda, including student recruitment, transforming the PGR international placements through Turing and other mobility schemes, building several successful international research partnerships, coordinated numerous UG and PGT partnerships and joint PhD programmes, and led the QS submission for the University as a 'QS Impact Champion'.

Earlier, he served as a Reader (2015-2017), Senior Lecturer (2012-2015) and Lecturer (2009-2012) before promoting to Chair and Full Professor of Air Quality and Health (2017-) at the ºÚÁÏÉç. He was the Deputy Director of Research for the Department of Civil & Environmental Engineering during 2018-2021.

An engineer by training, Prof Kumar obtained his PhD (Engineering) from the University of Cambridge (UK) after winning a Cambridge-Nehru Scholarship and Overseas Research Scholarship award. He earned his Master's Degree in Environmental Engineering & Management from the Indian Institute of Technology, Delhi, where he won the ‘Outstanding Postgraduate Student Award’ for his exemplary performance (CGPA 9.8/10 and rank 1). Prior to his PhD, he worked in the construction industry and a CSIR Research Institute for about 7 years.

Prof Kumar has won numerous prizes and awards in recognition of his academic and research excellence throughout his study and academic career. Consecutively in 2022 and 2023, he was bestowed with the global accolade of being recognised in the by Clarivate. The award reinforces Prof. Kumar’s ‘significant and continued broad’ contribution across scientific fields as one of the world’s top-cited researchers in Web of Science. He was the winner of the ºÚÁÏÉç’s Vice-Chancellor award ‘Researcher of the Year’ in 2017. His research on air pollution reduction through green infrastructure earned him the 2023 Haagen-Smit Prize for Best Paper.

Professor Kumar was honoured by the California Air Resources Board with the prestigious - an accolade regarded as the 'Nobel Prize' for air quality achievements - for his "transformative contributions, widespread impacts, novel accomplishments, and exceptional leadership and achievements in this field".

His fundamental and application-oriented cross-disciplinary research is focused on the interfaces of clean air engineering, human health and smart/sustainable living in cities/megacities. His current research projects are focused on broad multidisciplinary areas of air pollution monitoring/modelling, low-cost sensing, nature-based solutions, climate change mitigation and developing innovative technological and passive (e.g. green infrastructure) solutions for air pollution exposure control for both developing and developed world. He is currently the lead PI on the UKRI (EPRC, NERC, AHRC) funded .

In response to the global public health crisis, Prof Kumar played an active role in the clean air community. He participated in the Royal Society Rapid Assistance in Modelling the Pandemic (RAMP) volunteer initiatives and was part of an international effort making a case to the WHO for the recognition of airborne transmission. Among others, his team studied the impact of lockdown on air quality in different cities, including ODA countries, and how different types of face masks can offer protection from the infection of SARS-CoV-2 in public built spaces.

A prolific author with over (and the same number of conference presentations and articles), his research has attracted over , with an h-index of 80 (i10-index, 338). These include several highly downloaded, cited and almetrics articles, new directions around , , , and agenda-setting papers in the area of , , , , , and .

He has secured over £14M of individual research funding from projects total worth over £30M, funded by the RCUK (e.g,  EPSRC, ESRC, NERC, AHRC, MRC, HEFCE, British Council, Innovate UK, Research England, GCRF), industry, international funding bodies (e.g., European Commission, Qatar National Research Foundation, Commonwealth Commission, FAPESP) and charities (e.g. Ove Arup Foundation, RSA, Impact on Urban Health, Global Action Plan).

He serves on editorial boards of several international journals (e.g. Scientific Reports) and scientific evaluation panels of numerous funding agencies. He is Editor-in-Chief of the air quality section of the ‘Atmosphere’ journal (since July 2020) and founding Speciality Chief Editor of the ‘Climate Change & Cities' section of Frontiers in Environmental Science journal. He serves the editorial board of several reputed journals (e.g. Scientific Reports) and is Editor-in-Chief for the ‘Atmosphere’ journal (since July 2020) and founding Speciality Chief Editor of the ‘Climate Change & Cities' section of Frontiers in Environmental Science journal.

He is a reviewer and advisor to scientific evaluation panels of numerous funding agencies in the UK (e.g. NERC, EPSRC) and outside (e.g. Austrian Science Fund) and sits on the scientific advisory board of a number of companies. He advises local councils, and national and international governmental bodies on air pollution and urban nexus.

He has developed a network of collaborators across four continents. His research has featured regularly in well-read media outlets such as the BBC and The Times.
