Phil Gassman works as a research agricultural engineer in Resource and Environmental Policy at CARD. He received his B.A. and M.S. degrees in agricultural engineering from Iowa State University, and joined CARD in 1987. His research efforts support the integration of environmental and economic models that are used to assess policy scenario impacts for watersheds and other regions.

Gassman has worked on such varied projects as analysis of the risks and benefits of herbicide use, soil erosion and soil nitrogen loss studies, atrazine leaching in the Midwest, the impacts of alternative practices of livestock operations, and the nature of hog confinement odor. Currently, he is collaborating with ISU Extension and the Texas Institute for Applied Environmental Research (TIAER) on a modeling study for a watershed in the Maquoketa River Basin in eastern Iowa. He is also working with several Resource and Environmental Policy researchers and others at ISU on a watershed study of the entire Upper Mississippi River Basin. These studies will assess both the environmental and the economic impacts of different management practices on the watersheds.
