Research Interests

Meat safety; meat quality; shelf-life of meat and meat products; post-harvest foodborne pathogen control; characterizing pathogen and whole microbial community profiles present in meat production chain; effect of feeding system on degree of antimicrobial resistance and pathogen prevalence in livestock and poultry.

My research interests include the evaluation and validation of new antimicrobial chemicals and interventions against foodborne pathogens, as well as the investigations of the influence meat safety strategies have on the quality and shelf-life of meat products. In addition to applied investigations of meat safety, I also plan to continue my research characterizing degree of antimicrobial resistance, pathogen and whole microbial community profiles present in different meat and poultry production chains in order to gain a more comprehensive understanding of how pathogens and bacteria interact with different food matrices using novel technologies, such as next generation sequencing. Overall, the goal of our research is to continue to assist in industry efforts to deliver highly safety, affordable meat that are high in quality and nutritional values to national and global consumers.
