Dr. Erin Hodgson started working in the Department of Entomology, now the Department of Plant Pathology, Entomology, and Microbiology, at Iowa State University in 2009. She is a professor with extension and research responsibilities in corn and soybeans. She has a general background in integrated pest management (IPM) for field crops. Dr. Hodgson's current extension and research programs are focused on improving corn and soybean production by using IPM tactics to protect yield and increase overall farmer profits. Among other projects, she oversees insecticide efficacy evaluations for soybean aphids, Japanese beetles, and aphids in corn. Erin also helps manage emerging field crop pests and invasive species.

Dr. Sotirios Archontoulis is an assistant professor of integrated cropping systems at the Department of Agronomy. His main research interests involve understanding complex Genotype by Management by Environment interactions and modeling various components of the soil-plant-atmosphere continuum. Dr. Archontoulis's overall goal is to investigate practices that can increase the efficiency of system by means of increasing crop yields and simultaneously decreasing inputs or losses such as water and nitrogen. His approach combines field experimentation and use of mechanistic simulations models.
