I am fascinated by zoo and wildlife pathology, and I have special interest in neuropathology and conservation medicine. I have been working with histopathological and immunohistochemical aspects of neurological diseases in zoo and wild animals, trying to understand the pathogenesis of lethal diseases such as rabies in carnivores and bats and also PDD in psittacine birds, which was the subject of my PhD dissertation in Veterinary Pathobiology at Texas A&M University. I am currently Professor of Avian Pathology at the Federal University of Paraiba (UFPB). Brazil https://orcid.org/0000-0001-8688-9864
