Dr. Mohammad Al-Hamdan is a Senior Research Scientist with the Universities Space Research Association at NASA Marshall Space Flight Center. His research expertise includes Remote Sensing and Geographic Information Systems (GIS) applications to environmental modeling and assessment for water, air quality, urban heat island, ecological and public health applications; impacts of land cover land use and climate changes on water quantity and quality, air quality, public health, urban and aquatic ecosystems sustainability; developing decision support tools for different water, air quality, public health and ecological applications to improve decision-making and environmental sustainability; water flow resistance characterization using spatial analysis of remotely sensed data and GIS; Use of remote sensing for soil moisture estimation and water resources planning and management. Dr. Al-Hamdan has led the development of spatial algorithms and the spatial linkage and integration of remotely-sensed environmental datasets into several national decision support systems, models and online data systems, such as the CDC WONDER and EPHT environmental health systems, USGS SPARROW water quality system and NOAA Gulf of Mexico Data Atlas. Over the last eighteen years, Dr. Al-Hamdan has led and/or worked on several research projects funded by NASA, NIH, CDC, EPA, NSF, NOAA, DOD, USGS and/or USDOT with total grants of over $21 million, which resulted in numerous peer-reviewed journal, conference and technical report publications, and several national and international scientific achievement awards. Dr. Al-Hamdan holds Ph.D. and M.S. Degrees in Civil and Environmental Engineering from the University of Alabama in Huntsville.
