Dr. Ashima Sharma works in the field of global sustainability challenges, with a key focus on research pertaining to air quality management, atmospheric trace pollutants, atmospheric processes, and climate change. Her doctoral work sought to understand the relationships of ground-level ozone with its precursors and meteorological parameters over an urban atmosphere.

She has published several research papers and book chapters in reputed international journals and presented her work at different conferences and seminars. Her experience in academics includes teaching both undergraduate and postgraduate students.

She has served as a reviewer for reputed journals like Atmosphere, Sustainability, etc. She has been a recipient of various national and international honors from different agencies and organizations like the “Early Career Earth Science Researcher Recognition” from SAMEECSN- iLEAPS (South Asian and Middle East Early Career Scientists Network-Integrated Land Ecosystem-Atmosphere Processes Study) by International Early Career Scientist community, 2022; “Best Research Paper Award” and “Young Scientist Poster Award”, from Metrology Society of India & Springer-Nature; “Junior and Senior research fellowship” from University Grants Commission, among others.
