Research and Teaching Interests
Our group's major research interests include microbiome and metagenome techniques, host-microbe interactions, microbial ecology, bioinformatics, epidemiology, artificial intelligence and pathogen surveillance methods.
Our research is involved in developing practical ways to leverage the microbiome to improve food safety, and expand food production animals' production efficiency.
Our projects span from food safety testing to microbial profiling and targeted treatment/nutrition of livestock, and microbiome modulating approaches to impact animal health and productivity.
