Research Areas

My research program has two foci: diseases that affect the production and utilization of seeds;  and epidemiology and management of mycotoxigenic fungi in corn. Currently we are working on:

  • Interactions among seedborne viruses and fungi in soybeans
  • Impacts of lesion nematodes and seed treatment on fungi infecting corn seedlings
  • Detection of seedborne bacteria in edible bean seeds
  • Occurrence and effects of Fusarium fungi that infect soybean roots
  • Effects of transgenic insect resistance on infection of corn by mycotoxin-producing fungi
  • Impacts of mycotoxins in ethanol processing and co-product utilization

Professor, Extension Plant Pathologist

"What excites you about your job? I have a great job! Every day is different. Since I work with many crops (fruit, vegetables, ornamentals, shade trees, and turfgrass), and am heavily involved in research, teaching, and extension, I get to interact with students, colleagues, and all sorts of other Iowans. I especially enjoy working with graduate students and undergraduate interns." Read More
