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
