Professional Responsibilities and Activities
- Teaching
Dr. Loy is lead instructor for VMED 688 Public Health and a co-instructor for BIOS/VBMS 441/841 Pathogenic Microbiology. - Research
Dr. Loy's research interests include development and validation of novel molecular and proteomic diagnostic methods, pathogenesis and ecology of opportunistic bovine bacterial respiratory and ocular pathogens and enteric diseases of swine. - Outreach
As a diagnostic microbiologist, Dr. Loy is involved in assisting veterinarians and their clients, livestock producers and other stakeholders in the diagnosis, detection, and prevention of infectious disease. The VDC bacteriology laboratory also provides analysis and data to help inform veterinarian's decisions on prudent treatment of pathogens through performing antimicrobial susceptibility testing.
