Daryl R. Strohbehn, retired extension beef specialist and staff member of the Iowa Beef Center, coordinated education and outreach in cow-calf production for Iowa State University Extension from 1974 to 2010. A native of Iowa, Strohbehn grew up on an Angus seedstock cattle and grain farm. He received his bachelor's degree at Iowa State University and then his master's and doctorate at Michigan State University.
Strohbehn is recognized in the Cornbelt for his work in cow-calf production systems that utilize on-farm resources and correct genetic programs to yield profit. He pioneered Beef Cow Business Records, and more recently worked in team efforts to develop computer software packages geared toward problem-solving for producers. These included the very popular estrous synchronization planner and the BRANDS nutritional package from the Iowa Beef Center.
In recent years Strohbehn worked on feed efficiency evaluation with producers and did research work with a set of nursing Angus females. Additionally, he has worked with the TriCounty Steer Carcass Futurity Cooperative to produce the Sire Profitability Summary and its benchmarking program.
Strohbehn was a founding member of the Production Angus Associates in Central Iowa and still remains as a managing partner in that business.
Sally Northcutt is the genetic research director for the American Angus Association and Angus Genetics Inc. Her primary responsibilities include selection tool development, beef cattle data analysis, and the modeling and application of the National Cattle Evaluation. She also works with universities and ARS scientists across the nation to coordinate the expansive research activities of the Association.
Before coming to the Association, Northcutt was an extension beef cattle breeding specialist for nine years at Oklahoma State University, and she directed the Oklahoma Beef Inc. (OBI) central bull test at Stillwater. She is actively involved in industry organizations, such as the Beef Improvement Federation, in which she has served in various leadership roles during the past 14 years.
A Kentucky native, Northcutt received her bachelor's and master's degrees from the University of Kentucky and her doctorate in beef cattle breeding and genetics from Iowa State University.
Brian Brigham is the genetic systems director at Angus Genetics Inc. His primary focus includes new trait development and improvements such as genomic enhancements to national cattle evaluations.
Prior to joining the Association staff, the Colorado native was a research associate at Colorado State University, where he ran a variety of expected progeny differences (EPDs) for several different U.S. breed associations while concurrently working on both a master's degree and a doctorate in beef cattle breeding and genetics.
While at CSU, his research focuses included development of decision-support software, improvements in stayability predictions, carcass trait evaluations and genetic indicators of bovine respiratory disease. He was also a key investigator in the National Beef Cattle Evaluation Consortium project on cattle health.
In addition, while at CSU he worked part-time on projects with AGI over the last few years. His most recent work has focused on the productive life (longevity) evaluation for Angus cattle.
Tonya Amen is the genetic services director for Angus Genetics Inc. Amen assists in coordinating genetic education and outreach programs tailored to Angus breeders and commercial cattle producers. In addition, she interacts with Association entities to enhance strategic development of predictable supply chains using the available technologies and networks.
Amen is a native of Colorado and received a bachelor's degree in animal science from Texas Tech University. She also earned a master's degree and a doctorate in animal breeding from Texas A&M University.
For the past two years, Amen served as a cattle genetics specialist in the southeastern United States with Pfizer Animal Genetics. Prior to Pfizer, Amen served as an assistant professor at the University of Wisconsin in River Falls. She is also active in industry activities and currently serves on the NCBA Young Producers Council.
Megan Rolf joined the faculty of the Department of Animal Sciences at Oklahoma State University in June of 2012 as assistant professor of beef cattle management and state beef cattle extension specialist. Her extension goals include increasing awareness and understanding of genetic and genomic selection tools within the beef industry.
Rolf was raised on a small cow-calf operation in east-central Kansas near LeRoy. She earned a bachelor's degree in animal sciences with a science option at Kansas State University in 2005. While there, she worked in the school of veterinary medicine, where she was introduced to immunology and virology wet lab research while completing her animal science honors program research related to cytoplasmic inheritance.
Rolf relocated to Columbia, Mo., to pursue a master's in animal science at the University of Missouri, with a focus on use of SNP data to generate genomic relationship matrices. She also examined the use of model-predicted feed intakes in tandem with genomic data for the improvement of feed efficiency.
After completion of her master's degree she pursued a doctorate in genetics at MU, with a research focus on the exploration of methods to separate training and validation populations for improving across-breed genomic selection models for carcass traits. She was a graduate student association representative, graduate student peer mentor and a participant in the Genetics Area Program while at MU. Rolf currently resides in Stillwater, Okla.

Jude Capper is a self-employed sustainability consultant and an adjunct professor in the Department of Animal Sciences at Washington State University.
Capper's current research and outreach work focuses on modeling the environmental impact of livestock production systems, specifically dairy and beef. Her principal professional goal is to communicate the importance of livestock industry sustainability and the factors affecting it to enhance the knowledge and understanding of stakeholders within food production from the rancher and farmer to the retailer, policy-maker and consumer.
To this end, in 2011, Capper presented 35 invited presentations at national and international (New Zealand, Canada, Norway, Ireland, Italy and UK) conferences.
Current research projects include comparisons of historical and modern production practices in dairy and beef industries; and the effect of technology use and management practices upon environmental impact. She has an active social media presence and spends a considerable amount of time de-bunking some of the more commonly heard myths relating to resource use and the environmental impact of livestock production.
