Dr. Mary Oluwatomisin Elijah is a veterinary pathologist, academic and researcher with interests spanning veterinary diagnostic pathology, clinical pathology, infectious diseases and artificial intelligence-assisted diagnostic microscopy. She holds a Doctor of Veterinary Medicine (DVM) degree from Ahmadu Bello University, Zaria, and a Master of Science (MSc) degree in Veterinary Pathology from the same institution. Her doctoral research in Veterinary Pathology focused on integrating conventional clinicopathological investigations with artificial intelligence and machine learning for the diagnosis and characterisation of parasitic diseases.
She is a Lecturer II in the College of Veterinary Medicine at the Federal University of Agriculture, Abeokuta, where her academic and professional activities include veterinary pathology teaching, diagnostic services and clinical pathology. Her diagnostic interests encompass haematology, blood film evaluation, clinical biochemistry, cytology, urinalysis, microscopy and post-mortem examination. Her work combines morphological assessment with quantitative laboratory data to support disease investigation and veterinary diagnosis.
Her research interests include infectious and parasitic diseases, haematological alterations associated with disease, diagnostic pathology, computational pathology, digital microscopy and artificial intelligence-assisted image analysis. A major component of her research is the development and evaluation of machine learning and deep learning approaches for the detection, classification and quantification of pathogens and cellular morphological abnormalities in veterinary blood smears. Her doctoral research particularly explores automated microscopic detection of Trypanosoma brucei and erythrocyte alterations in experimentally infected laboratory animals.
Dr Elijah is also interested in the application of artificial intelligence to low-resource diagnostic settings, with particular emphasis on smartphone-assisted microscopy, computer vision and automated interpretation of clinical pathology data. Her broader academic goal is to contribute to the development of accessible, reproducible and computationally supported diagnostic approaches in veterinary medicine.
She participates in professional activities in veterinary pathology and clinical pathology and is committed to teaching, research, diagnostic service and interdisciplinary collaboration at the interface of veterinary medicine, pathology and emerging computational technologies.
