Dr. Alok Sagar Gautam is Assistant Professor, Department of Physics, Hemvati Nandan Bahuguna Garhwal University (A Central University) Srinagar Garhwal Uttarakhand India. My main research area is Atmospheric Science which has significant impacts on society. Research focuses on measurements and characterization of trace gas and aerosol; dry and wet deposition; bioaerosol; biomass combustion, emission and control; climate change and public health; Environmental accounting.

He has reported roles of Lenard and Blanchard effects in generating excess of negative intermediate ions in the initial stages and excess of positive cluster ions, in the later stages of a rain shower, respectively. He has also developed a model for the generation of ions over tropical region.

Presently, He is involved to investigate the impact of aerosols on Cloud Condensation Nuclei (CCN) and its properties, to estimate the intra-seasonal, inter-annual and long-term variability in size-resolved CCN properties, to investigate interplay between aerosol, cloud and rainfall over Garhwal Himalalaya region. His work is interesting and has significant impact on climate change, public health and society. Nominee has to his credit more than twenty five research papers in National and International journals of repute including two in world top rank Journal “ Quarterly Journal of Royal meteorological Society, Journal of Geophysical Research” in the area of Earth and planetary science. Nominee has presented/contributed research papers in more than 60 National and International Seminar/Conferences. His work has been highlighted in the form of prestigious National and International Awards and fellowships such as the Young Scientist Award by Uttarakhand Council of Science and Technology Congress, Department of Science and Technology (DST), Government of India, Indian National Science Academy Summer research fellow, Junior Associate (2012-2018), Earth System Physics by the Abdul Salam International Centre for Theoretical Physics (ICTP), Trieste Italy, International Travel fellowship by Science and Engineering Research Board– DST (SERB-DST) Government of India to attend the International Conference on Atmospheric Electricity (ICAE) Rio de Janeiro Brazil (August 7-12, 2011) & to attend the European Aerosol Conference (EAC -2015) at Milan Italy (September  6-11, 2015), Environmentalist of the year 2019 award by International Foundation for Environment and Ecology, February 24, 2020, Research Excellence Award by Institute of Scholars Bengaluru, “Young Scientist Award” in Atmospheric and Space Science by Glocal Environment & Social Association (GESA) New Delhi on Oct 20 2019, “Best oral and poster Award” on International Conference on Aerosol, Air Quality and Climate Change on Himalayan region of Uttarakhand” by Department of Physics, HNBGU Srinagar  India, 21-23 October 2018, Young Scientist of the year Award 2018 by International Academy of Science and Research (IASR), Kolkata, Promising Indian Award in Science and Technology by Promising Indian Society Delhi, Clean Environment Promotion Award by IBRF Kolkata.

He has delivered many invited talks in India and abroad including few popular science lectures on the topic "Air Pollution and Health" which was broadcasted by All India Radio, Pauri, in Pauri Garhwal 2019. He is Editor-in-Chief of peer reviewed scientific Journal of Science and Technological research (JSTR), Assistant Editor of Asian Journal of Physics. Nominee is an active member of “Cloud-Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX)” Campaign. He is life member of number of scientific bodies viz., The Indian Science Congress Association; American Geophysical Union; The Society of Earth Scientists, Lucknow, Indian Physics Association; Indian Association of Physics Teachers; Indian Association for Radiation Protection; Indian Meteorological Society; National Society of Aerosol, Air Quality and Climate Change Research; IASR Kolkata; Glocal Environment & Social Association (GESA) New Delhi; Institute of Scholars Bengaluru; Indian Association of Societal Development. He is/was involved in a number of research projects sanctioned by different funding agencies viz., SERB-DST and DST, MHRD. He is reviewer of number of International journal viz., Journal of Geophysical Union, International Journal of Environmental Monitoring and Analysis, Acta Ecologica Sinica, Journal of Environmental Science and Engineering etc. He has organized many conferences/seminars/essay writing competition/poster competition for spreading awareness and capacity building.
