Roberto Diaz, MD, PhD, FRCS(C)
Dr. Diaz’s laboratory is in the Brain Tumour Research Centre, where he will use molecular biology techniques to study how brain cancer cells develop and find ways to stop their growth without toxic effects to normal cells in the body.
Dr. Roberto Jose Diaz is a neurosurgeon and Assistant Professor of Neurology and Neurosurgery at Ï㽶ÊÓƵ who specializes in the neurosurgical treatment of brain tumours. His research at The Neuro's Brain Tumour Research Centre focuses on understanding fundamental molecular mechanisms that regulate the development of cancer in the brain.
Model systems, genetic tools, and biochemical assays are used to understand how brain cancer cells originate, replicate, survive, and migrate. By understanding the basic processes that allow tumours to develop, smart medicines can be developed which will be less toxic to normal cells and effectively seek and destroy brain cancer cells. The laboratory also studies new strategies for delivering drugs and biological agents across the blood-brain barrier, which prevents many useful chemotherapy agents from entering the brain.
In addition to basic science research, Dr. Diaz leads a clinical research program. His main areas of research are the assessment of targeted therapies for malignant brain tumours and the development of minimally invasive surgical tools for brain tumour diagnosis and treatment.
