Research
I have had a research career with the U.S. Department of Agriculture and U.S. Geological Survey for more than 34 years before joining the Department of Geological and Atmospheric Sciences. . My general research interests include quantitative techniques to assess and estimate water quality responses to agricultural activities at a regional scale. Most recently I have been studying how to reduce agricultural nitrogen loads to streams and develop methods to allocate source-loads of nutrients that may impair water resources. I also lead a group of scientists developing nutrient criteria for lakes and streams in Iowa.
