Oliveira became head of
clinical neurology and head of the
biochemistry course at the University of Coimbra in 1988. Her research has focussed on the molecular mechanisms of
neurodegeneration and
neuroprotection, emphasising the interaction between research and the clinical treatment of neurodegenerative diseases. She has coordinated several scientific projects, including on the mechanisms of brain ageing and dementia, and on the relationship between
diabetes and neurodegenerative diseases. Most recently she led a research group dedicated to advanced diagnosis and identification of biomarkers of ageing and brain diseases, part of a European consortium working in this area. Oliveira is a consultant in neurology at the Neurological Clinic of the
Centro Hospitalar e Universitário de Coimbra (Coimbra University Hospital - CHUC), a member of the Alzheimer Portugal scientific committee and president of the Portuguese Agency for Clinical Research and Biomedical Innovation (AICIB). She coordinates the consortium that brings together the Centre for Neuroscience and Cell Biology and the
Instituto Biomédico de Investigação em Luz e Imagem (Biomedical Institute for Research in Light and Image - IBILI). Oliveira is a director of the Innovation and Development Unit of the CHUC. She was a member and later president of the Scientific Council for Life and Health Sciences of the
Fundação para a Ciência e Tecnologia (Foundation for Science and Technology), which is the organization in Portugal that decides on funding allocation for research. She has been a reviewer for the
Wellcome Trust, the
Alzheimer's Association,
Parkinson's UK, the
Medical Research Council (MRC) and the
European Research Council (ERC). She is member of the
European Dana Alliance for the Brain (EDAB), and was sub-director of the Portugal/
Harvard Medical School Programme. ==Awards and honours==
