Biography

Dr. Clay received a B.S. in horticulture fro the University of Wisconsin Madison, a M.S. in plant science from University of Idaho and a Ph.D. in agronomy from the University of Minnesota. She has conducted weed management studies in cropping systems including corn, soybean, wheat, barley, flax, sunflower, safflower and rangeland. Studies have included weed physiology, the influence of weeds on crop growth and genomic responses and site-specific weed management strategies. She has published over 200 scientific articles and has served as editor on several books and associate editor for Weed Science and technical editor for Agronomy Journal. She has been co-author of four best papers of the year. She has served on numerous national committees and grant review panels. She was elected American Society of Agronomy fellow in 2009 and served as the president in 2013. In 2017 she was awarded the Gamma Sigma Delta International Distinguished Achievement in Agriculture 啵啵直播秀 and in 2019 the ASA/CSSA/SSSA Mentoring 啵啵直播秀.

Weed biology and physiology.
Crop/weed interactions including corn, wheat, barley, oil seed crops (sunflowers, flax, soybean), rangeland and pastures.
Precision agriculture to assess weed variability across landscape positions.
Herbicide-soil-antibiotic interactions to limit or eliminate herbicide contamination of surface and ground water.
Transcriptome and stable isotope (13C and 15N) analysis explore weed-crop interactions on corn and soybean, crop effects on weeds and abiotic stress effects on corn.
Nonchemical options for weed control including tillage, crop rotations, cover crops, grit sprayer applications and biocontrol options.
