Expertise / Research Area

Dr O'Connor has two main areas of research interest. The main area of focus has been understanding how researchers can use study design and review methodologies to better translate primary research findings into useful decision support tools. Primarily this work has focused on how to adopt and adapt the systematic review methodology used in clinical medicine to veterinary science and food safety. This area has resulted in several papers about how to review primary research in veterinary science and food safety. Further, this body of work has resulted in the production of the REFLECT statement (www.reflect-statement.org) which is a guide for authors, reviewers and editors on how to report intervention studies in a manner that increases their utility to end users including practitioners and risk assessors.


In the area of work that relates to the epidemiology of infectious disease that affect livestock populations, Dr O'Connor has focused on understanding the epidemiology and control of Pinkeye in beef cattle. Studies have included observational studies that evaluate the role of putative causal organism in Pinkeye and randomized field trials that evaluate the efficacy of vaccine designed to prevent Pinkeye occurrence.  Consistent with the theme of increasing translation of primary research for decision makers Dr O'Connor has also co-authored several reviews evaluating the treatment and control of Pinkeye.

 

The other organism of focus for Dr O'Connor has been the epidemiology of Salmonella in pork with emphasis on understanding pre-harvest control approaches.   Dr O'Connor has worked on several primary research studies that have evaluated the methods of detecting farms with a high risk of carrying Salmonella spp. into the slaughterhouse. Again, Dr O'Connor has also co-authored several reviews evaluating the treatment and control of Salmonella in the pre-harvest environment.

 

Teaching

Dr O'Connor teaches primarily in the graduate curriculum. She teaches an introductory course for epidemiologists, and a course in applied logistic regression methods.
