Research

I am involved in the application of epidemiologic principles and methods to the study of disease agents associated with livestock and related food products. My focus is on food safety and animal health research with a primary emphasis on beef cattle. Much of my food safety research has been on E. coli O157:H7, other Shiga toxin-producing E. coli, and Salmonella, but I am also involved in several other areas of food safety research. My animal health research has been on the use of clinical, diagnostic, and/or demographic data for assessing the health status of livestock populations. We are currently focused on the utilization of operational feedlot data for making evidence-based animal health decisions. Additional research interests include the development and application of methods for monitoring disease burden and validating diagnostic strategies; combining molecular and epidemiologic data for defining the epidemiology of infectious diseases; and the application of valid epidemiologic study design, implementation, and data interpretation for field-based research in commercial production systems.

Teaching

My primary teaching role is to further develop professional and graduate student training in epidemiology.  I help teach an introductory course on epidemiology in the first year of the professional veterinary curriculum (Principles and Methods of Epidemiology), and three graduate courses – Disease Epidemiology, Design and Interpretation of Epidemiologic Research, and Applied Production Medicine.  I also deliver several guest lectures in other courses, and advise DVM, MPH, MSc, and PhD students.
