He collaborates with the larger global earth science community on training and research. Previously, Dr. Gupta served as the portfolio manager for SERVIR's Applied Science Team. He managed more than 20 research projects spread out across multiple applied science research areas and operational in more than 30 countries. He has experience working with stakeholders, including US government agencies, state and local agencies, non-profit and private sectors, and international agencies (World Bank, WHO). Dr. Gupta's research expertise includes remote sensing methods, data product development, validation, and application development. He has also published more than 50 peer-reviewed research studies focusing on satellite algorithms, air quality, climate, statistical modeling, and machine learning and data fusion techniques. Dr. Gupta is the principal investigator on NASA-funded research projects. He is currently a member of NASA's multiple missions and science teams, including MODIS and VIIRS, NASA's citizen science, Making Earth System Data Records for Use in Research Environments (MEaSUREs), and the Health and Air Quality Applied Science Team (HAQAST). Dr. Gupta is also the lead for a HAQAST tiger team funded by NASA to integrate satellite data into EPA's AirNow air quality monitoring system.
