Hameetman Science Center 208

Dr. Sadd teaches courses in Geographic Information Systems in which students evaluate many types of information using spatial analysis and statistical tools.

Dr. Sadd also uses GIS and other geospatial and statistical tools in his research to evaluate environmental problems, such as human exposure to environmental hazards, patterns or health risk and vulnerability, and environmental justice/equity, particularly as it relates to air pollution and climate change. He also works on questions related to coastal erosion, and marine habitat distribution and change.
