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.

Daren Mueller is an associate professor and extension plant pathologist at Iowa State University. He is also the coordinator of the Iowa State Integrated Pest Management (IPM) program. Daren received his bachelor's degree from the University of Wisconsin-Madison in 1996, and his master's degree and doctorate in Plant Pathology from the University of Illinois-Urbana in 1999 and 2001. Daren’s main research interests involve understanding the biology and management of field crop diseases. Daren is also a co-director of the North Central IPM Center and the Crop Protection Network.

Dr. Alison Robertson is a professor of plant pathology and microbiology. She provides extension education on the diagnosis and management of corn and soybean diseases. Her research interests include Pythium seedling disease of corn and soybean and Goss's wilt. Dr. Robertson received her bachelor's degree in plant pathology in 1991 from the University of Kwazulu-Natal, Pietermaritzburg, and came to the United States in 1999 to pursue a doctoral degree in plant pathology at Clemson University. She started working at Iowa State University in May 2004.

Adam Sisson is an extension specialist with the Iowa State University Integrated Pest Management (IPM) program and a Certified Crop Adviser. Sisson focuses on the development of publications and other educational resources for farmers, agribusiness, and students. He received his bachelor's degree in agronomy and environmental studies in 2006 and a master's degree in sustainable agriculture in 2009; both from Iowa State University. 

Dr. Mark Licht is an associate professor and extension cropping systems specialist with Iowa State University Extension and Outreach. His extension, research and teaching program is focused on how to holistically manage Iowa cropping systems to achieve productivity, profitability and environmental goals. Research is centered around varied aspects of soybean, corn and cover crop management as well as agronomic implications of precision technologies.

Meaghan Anderson is a field agronomist in central Iowa and an extension field specialist at Iowa State University Extension and Outreach. Educational programming is available for farmers, agribusinesses, pesticide applicators, certified crop advisors, and other individuals interested in crop production.

Areas of expertise include weed management, weed biology, cover crops, corn and soybean management, and integrated pest management.

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.

Dr. Kathleen Delate's current position as a professor and extension organic specialist at Iowa State University is a joint position between the departments of horticulture and agronomy, where she's responsible for research, extension, and teaching in organic agriculture. Organic agriculture is now a $35 billion industry in the United States, with 18,000 organic farmers. Her research focuses on pest management and soil fertility management strategies for transitioning and certified organic farmers.

Dr. Delate grew up on the East coast where her father was a statistician for Dupont and her mother hailed from a family farm in Magnolia, Minnesota. She spent many summers working on her cousin’s diversified farm in Minnesota, helping bale hay and feed hogs, which is where she developed a love for agriculture. Dr. Delate earned her bachelor's degree in agronomy, a master's degree in horticulture from the University of Florida, and a doctoral degree in agricultural ecology from the University of California-Berkeley. She has farmed organically in Iowa, California, Florida, and Hawaii. In 2014, she spent a sabbatical in Italy, studying organic no-till farming with some of the 48,000 organic farmers there. A video on the organic no-till system is available at: https://vimeo.com/user20353817/review/99643832/0a09248894
