Dr. Sneha Gautam Sneha is an Associate Professor in the Division of Civil Engineering at Karunya Institute of Technology and Sciences, Coimbatore, India. He earned his PhD (Engineering) from Indian Institute of Technology, Kharagpur and an MTech (Environmental Science and Engineering) from IIT-ISM Dhanbad. After his PhD, he joined INCLEN and the University of California, Berkeley, as a researcher, followed by a Post-Doctoral Fellowship from the Ministry of Science and Technology, Taiwan, and pursued postdoctoral research at NCTU, Taiwan. His name has been featured consecutively (2021-2024) in Stanford University's Top 2% Scientists of the World list. He has received numerous awards, including the Young Scientist Award 2023 by the Academy of Sciences, Chennai, Young Scientist Award 2022, IEI Special Appreciation Award 2021, IEI Young Achiever Award 2020, IEI Young Scientist Award 2019, Outstanding Reviewer Award from Elsevier, and an International Travel Grant from the Government of India. He also serves as an Editor, Associate Editor, and Editorial Board Member for several high-impact journals, including those by Nature (Scientific Reports), Springer (e.g., Water, Air and Soil Pollution, Stochastic Environmental Research and Risk Assessment, Environmental Development and Sustainability, Asia Pacific Journal of Atmospheric Sciences, SN Applied Sciences), and Elsevier (Gondwana Research, Spatial and Spatio-temporal Epidemiology). With over 145 articles in leading journals (h-index 39, i10-index 89, and over 5070 citations), he has developed a global network of collaborators and his research has been featured in prominent media outlets such as Al Jazeera, The Times of India, and Trinity.Dr. Alok Sagar Gautam is working in the Department of Physics, School of Science, Hemvati Nandan Bahuguna Garhwal University (A Central University) Srinagar Garhwal Uttarakhand. His research area is Atmospheric Physics, Air Quality and Health, Weather and Climate Change & Environmental Sustainability and Consciousness. He has successfully completed 1 research project funded by SERB Delhi and one DST-funded project is ongoing. Dr. Gautam has visited Germany, Italy, and Brazil. He was a 28th Indian Scientific Expedition Member of South Pole Antarctica and did the research for 6 months.  He is an Associate with the Earth System Physics Group, the International Centre for Theoretical Physics (ICTP) Italy.  He is the recipient of many national and international awards viz., Young Scientist Award, Environmentalist of year and award, Research Excellence Award. In Uttarakhand, Dr Gautam has established the laboratory of Cloud Physics and forecasting of lightning.Dr. Amit Awasthi is Associate Professor at the University of Petroleum and Energy Studies, Dehradun, India. He completed his PhD from Thapar University, Patiala, in 2011, and has over 18 years of professional experience in the areas of research and development, teaching, and allied functions with reputed educational institutions and universities, offering research experience in atmosphere and environmental sciences including air monitoring, exposure studies, extreme events, water quality, climate change. He has the merit of receiving International Fellowship from National Science Council-Taiwan as Postdoc Fellow. He has published 4 textbooks and more than 60 research papers in reputed journals of atmospheric/environment sciences/climate change with an h-index 19 and citation ~ 1400 and impact factor ~250. He has received several research grants from national and international organizations in the areas of aerosol and water quality measurements. He has edited several books with reputed publishers such as Taylor & Francis, Elsevier, Springer. In addition to his research and teaching responsibilities, he is actively involved in various academic tasks such as university accreditation, organizing conferences, designing curricula, etc.Dr. Ramsundram N, an esteemed associate professor at Kumaraguru College of Technology in Coimbatore, Tamil Nadu, is a leading researcher in environmental engineering, specializing in air pollution and exposure. Having earned his doctoral degree from IIT Madras, he has gained recognition for his impactful research and numerous publications in renowned journals, underlined by his impressive citation record. Dr. Ramsundram's recent work explores the complex interactions between aerosols, air quality, and health impacts. He delves into the relationship between Aerosol Optical Depth (AOD) and particulate matter (PM2.5), utilizing predictive modeling to assess air quality and precipitation patterns. His studies have also revealed critical insights into how Body Mass Index (BMI) influences PM2.5 deposition in the respiratory system, showing how individual susceptibility to air pollution varies. His research has furthered understanding of occupational health risks through elemental analysis of PM10 and PM2.5 in environments such as auto-repair garages and households, revealing distinct exposures and health outcomes. Variations in age and gender are shown to affect how particulate matter is deposited in the body, leading to diverse health impacts across populations. Another notable area of his research examines how urban pollution affects ocular health, particularly with the accumulation of particles on contact lenses. Dr. Ramsundram has also investigated the effects of the COVID-19 pandemic on urban air quality, documenting how shifts in human activity influenced pollution levels. His work continues to illuminate the intricate relationships between environmental factors, aerosols, and human health, highlighting the need for ongoing research to address these pressing challenges.
