Philosophy: Collegiate level education should provide knowledge of subject material, but more importantly provide an environment where students learn to critically evaluate realistic problems and issues, formulate alternatives to resolve problems and questions, and select optimal solutions. In addition, collegiate education should train students to communicate effectively, both orally and written, in their professional fields and in other public venues.
Approach: First, I introduce or review the subject material (general knowledge). Next, I interact with students in lecture, homework and exams to ensure that students can think critically within subject material using what if scenarios problem recognition, and application of principles to new situations. I work hard to provide students a safe haven to practice critically thinking and problem solving. Using case studies and real life scenarios, I provide hands on opportunities, support and advice to use their knowledge and critical thinking abilities and analytical skills to answer questions and resolve problems. I try hard to get students to think out-of-the-box. Students practice oral and written communication through class discussions, projects, and exams, and I provide comments and feedback to help improve their communication skills.
Major Research Areas:
Targeted grazing, livestock behavior, grazing management, rangeland livestock production, riparian area management, and livestock adaptation
The focus of my research has revolved around livestock grazing distribution and rangeland livestock management. From 5 years working as a consultant, I found that undesirable grazing distribution was and continues to be the cause of many of the livestock grazing related issues on public and private lands in the western United States and around the world. Livestock grazing is often considered unsustainable because animals overgraze in some areas while other areas receive little use. Much of my research program is based on novel approaches to evaluate and refine rangeland and livestock management practices that were used and recommended to improve grazing distribution over 50 years ago. However, technology was not available 50 years ago to accurately monitor and analyze cattle grazing patterns. With modern GPS and GIS technologies, we can not only evaluate recommended practices, such as herding, strategic supplement placement and selection to manage livestock grazing, but we can develop methodology to make these practices more effective. Thus, we are not reinventing the wheel but rather understanding the processes and mechanisms of grazing behavior and using that information to refine livestock grazing management. If we understand these behavioral mechanisms, we can begin to use livestock, not only as a source of red meat, but as a tool to manage vegetation and habitat on western rangelands.
