Since the year 2000 Dahlen has been intimately involved in research efforts with a focus on reproduction, nutrition, and management of cattle and sheep. The emphasis of his current research program is to improve fertility in livestock species and to evaluate implications of nutrition and management strategies on reproductive and offspring outcomes. Dahlen joined the North Dakota State University faculty in 2010 as a Beef Cattle Extension Specialist where he engaged in integrated Extension and research efforts taking place on over 350 commercial beef operations. Dahlen was instrumental in developing innovative training methods that empower county, area, and state Extension personnel to better serve their beef-producing clientele. The unique mix of his research background and practical experience has led to several novel research techniques, data collection efforts, and training methodologies. Dahlen was an integral part of a team that developed and optimized a standing flank hysterectomy procedure that allows his group to achieve an exemplary combination of high-level science and fiscal responsibility. Publications using this model have been geared toward answering questions about developmental programming, focusing on implications of maternal nutritional management on offspring characteristics. In 2018 Dahlen transitioned to position that allowed him to dedicate more time to research, as well as teach undergraduate/graduate classes in reproductive physiology. A new facet of his research program has been dedicated to addressing whether paternal (i.e. sire) nutrition and management was not only impacting semen characteristics and molecular composition, but also implicit in offspring outcomes. Other recent efforts involve evaluating impacts of nutritional perturbations during gestation on offspring and transgenerational endpoints, and utilizing sheep as a biomedical model for women’s vaginal health.
