Brief Bio


John is Chief of the Hydrological Sciences Laboratory, NASA Goddard Space Flight Center, and he is serving as Associate Program Manager of Water Resources for the NASA Applied Sciences Program. He is also leading NASA's International Water Strategy.  His research focuses on the application of satellite-based remote sensing and land surface hydrological modeling for improved ecological and water resource management. He is involved in several water resources management efforts addressing flood monitoring, flood damage assessment, and agriculture drought forecasting and mitigation. He is leading projects in the Middle East, Central and North Africa, Southeast Asia, and United States. He has served on the Panel on Global Hydrological Cycles and Water Resources for the 2017-2027 Decadal Survey for Earth Science and Applications from Space. He is serving as NASA DEVELOP Program Lead Science Advisor for the NASA Goddard Space Flight Center. He has served as the NASA GRACE Mission Applications Deputy Representative for Water and Coastal Resources, Chair of the American Geophysical Union’s Hydrology Remote Sensing Technical Committee, and Co-lead on the Committee on Earth Observing Satellites (CEOS), Flood Disaster Pilot Risk Management Team. His most recent research includes the development of an improved hydrological decision support system for the Asian Disaster Preparedness Center and Mekong River Commission, development of the operational global soil moisture product for the USDA Foreign Agricultural Service crop forecasting system, and a deep learning-based system for improved satellite-based agricultural monitoring products. He has received multiple awards including the 2019 Arthur S. Flemming Award for Applied Science, the 2019 NASA Exceptional Scientific Achievement Medal, the 2019 Department of State award for supporting the drafting and implementation of the US Global Water Strategy, the 2019 Robert H. Goddard Award for Science, as well as multiple NASA Hydrospheric and Biospheric Sciences annual awards for Outstanding Scientific Achievement, and Outreach. John is very involved in the scientific community and regularly gives invited keynote lectures, seminars, and tutorials on his research as well as the activities of NASA’s Applied Sciences Program related to water resources management around the globe. He received the M.S. and Ph.D. degrees in geology with an emphasis in hydrology and remote sensing from the University of South Carolina.

February 2015 - Present

NASA scientist Dr. John Bolten talks about the launch of the Soil Moisture Active Passive - or SMAP - satellite scheduled to launch on Jan 29. SMAP will take stock of the water hidden just beneath your feet, in the topsoil. Knowing how much water is in the soil, and whether it is frozen or thawed, has profound applications for society, from better forecasting of natural disasters like floods and droughts to helping prevent food shortages.
