Dr. Catherine D. Carrillo
Current research and/or projects
Dr. Carrillo's current research program is focused on the application of whole-genome sequencing (WGS) technologies for the detection, identification and characterization of foodborne bacterial pathogens. In the past four years, Dr. Carrillo's laboratory has sequenced several thousand bacterial genomes, and this work has led to the implementation of methods for real-time WGS of bacterial pathogens isolated in CFIA's food testing programs. Her current research interests include the development of tools for bacterial phenotype prediction based on WGS data, and the application of novel technologies (e.g. metagenomics) to improve methods for detection of bacterial pathogens in foods. Dr. Carrillo currently leads the sequencing component of the interdepartmental Genomics Research and Development Initiative project on antimicrobial resistance (GRDI-AMR).
