My primary and active research areas involve diseases and injuries that occur at the human-animal interface. These often reflect new and emerging issues (i.e. C. difficile, MRSA) or evolving disciplines such as veterinary infection prevention in the clinic/hospital setting.
My laboratory focuses on the broad field of viral disease pathogenesis in domestic poultry species, more specifically on diseases that modulate host responses. My group is interested in the viral and host factors that determine transmissibility and viral adaptation particularly in how that relates to interspecies transmission (emerging and zoonotic diseases).
Anatomic pathology as it relates to infectious diseases, agriculture, public health and biomedical research
Dr. Goyal's research interests include diagnosis, pathogenesis and control of viral infections in livestock and poultry and the development of methods for the detection and prevention of human and animal viruses in food, water and environment.
Dr. Halvorson is interested in diseases of poultry with particular emphasis on the control and eradication of the same. He is also interested in applying biosecurity principles to enhance pre-harvest food safety. Research-based control strategies have been developed for avian influenza and avian pneumovirus.
Research to support public policy-making in the areas of animal health, food safety and public health. Using risk analysis tools to support decision-making for preparedness and response. One Health competencies and leadership
I have two primary research areas: 1) understanding the mechanisms of plasmid dissemination associated with antibiotic resistance in bacterial pathogens; and 2) understanding the succession of the microbial communities in the animal gastrointestinal tract related to health and development. I work primarily with multidrug resistance-encoding plasmids of E. coli and Salmonella humans and production animals. The goal of this work is to understand the spread of these plasmids within and between human and animal bacterial populations. I also work closely with the poultry industries to study the bacterial populations inhabiting the gastrointestinal tracts of turkeys and chickens. The goal of this work is to understand the succession of bacterial communities over time, and how the modulation of these communities can be achieved using non-antibiotic alternatives.
I have been transitioning from a primary focus on reproductive physiology in wildlife to more of a focus on emerging challenges at the intersection of livestock, humans, wildlife and the environment
My research is dedicated to the application of molecular and cytogenetic approaches to the study of genomics, immunogenetics and evolution.
Risk analysis of food safety and animal health issues Antibiotic resistance of foodborne pathogens
I seek to identify cost-effective and efficacious interventions for reducing foodborne pathogen contamination of meat and for minimizing the development and spread of antibiotic resistance in bacteria
I have been studying host responses and the underlying basic mechanism in animals and humans infected with avian influenza viruses. We are recently also exploring the emerging novel bunyaviruses that may be present in agricultural animals and pose a threat to animal and human health
Current focus is applied research of production poultry diseases.
