Research

My research emphasizes the application and extension of epidemiologic principles and methods to enhance animal health, food safety and security, and related impacts on human health.  By utilizing appropriate experimental, observational, and synthesis research methods, my outcomes-focused research enables valid data-driven decisions that improve animal health/well-being, food safety, production efficiency, sustainability, and economic viability of animal health systems.  My recent research is primarily focused on applying epidemiologic approaches to generate industry-relevant knowledge that is used to address complex and contemporary problems in the beef industry.  As the Director of the Center for Outcomes Research and Epidemiology, I am engaged in strategic development and implementation of research and training initiatives that enhance a wide-range of population health programs. 

Instruction and Mentoring

I teach, mentor, and enable students to develop sustainable knowledge, skills and abilities so that they can solve current and future challenges in their professional roles. I emphasize scientific validity, research integrity, and evidence-based health management decisions. My primary teaching role is to develop and deliver professional and graduate student training in epidemiology, particularly as it relates to animal health and food safety. In addition to creating and delivering continuing education and advanced graduate student training, I have taught clinical epidemiology and population health management to professional students every year since becoming faculty, and have advised DVM, MPH, MS, and PhD students.
