I am a native of Southwest Iowa. My academic training is mainly in electrical engineering. Between my undergraduate and graduate career I was a member of the Mississippi Teacher Corps, through which I taught high school chemistry and physics. I have courtesy appointments in the Departments of Electrical and Computer Engineering, and Geological and Atmospheric Sciences. I have been at Iowa State since 2003.
Satellite remote sensing allows me to use my training in radio science to study the environment. Most of my research focuses on the microwave region of the electromagnetic spectrum because of the unique properties of liquid water. I use microwave remote sensing as a tool to understand how water moves among the soil, vegetation, and lower atmosphere.
We are entering a new era of terrestrial hydrology. The first microwave remote sensing satellite mission that can produce global maps of soil moisture every two-to-three days was launched by the European Space Agency in 2009. NASA recently launched a similar satellite in early 2015. Initially these new data will be used to improve the predictions of weather and climate models. Eventually we hope to use this information to make better predictions of flood severity and extent, to estimate soil erosion, and to monitor the growth of crops.
