A/Professor Finnie has a particular interest in the pathology and pathogenesis of neurological diseases, with a major focus on brain lesions that can be diagnostically useful. These studies encompass naturally occurring neurological disorders of domestic animal species and the development of animal models of human nervous system diseases. The principal neurological diseases he has investigated are traumatic brain injury (blunt, non-missile, missile, and paediatric abusive head trauma), tunicamycin/corynetoxin and Clostridium perfringens type D epsilon toxin neurotoxicity and retinopathy, neuroaxonal dystrophy, riboflavin deficiency-induced demyelinating peripheral neuropathy, neurological effects of radiofrequency field exposure, and forensic neuropathology. His contributions to veterinary and comparative neuropathology have been recognised, by examination, with a Doctor of Veterinary Science from the University of Melbourne and a Fellowship of the Royal College of Veterinary Surgeons in the United Kingdom.
