Veterinary Pathology: Dr. Headley focuses on the study of diseases and abnormalities in animals, aiming to understand their etiology, pathogenesis, and clinical manifestations. His research may involve investigating the histopathological changes associated with different diseases in various animal species.

Veterinary Preventive Medicine: Dr. Headley explores strategies and interventions aimed at preventing diseases and promoting animal health. This may include research on vaccination protocols, disease surveillance systems, and biosecurity measures in veterinary practice.

Infectious Diseases: His research may encompass the study of infectious agents affecting animals, including bacteria, viruses, fungi, and parasites. Dr. Headley may investigate the epidemiology, transmission dynamics, and host-pathogen interactions of infectious diseases to develop effective control and management strategies.

Comparative Pathology: Dr. Headley may engage in comparative studies of diseases across different animal species, aiming to identify commonalities and differences in disease processes. This comparative approach contributes to a better understanding of disease mechanisms and may inform the development of diagnostic and therapeutic approaches.

One Health Approach: Dr. Headley may also be interested in research that integrates human, animal, and environmental health, known as the One Health approach. This interdisciplinary approach recognizes the interconnectedness of health between humans, animals, and the environment and seeks to address health challenges through collaborative research and interventions.
