Álvaro Ardiles is a biochemist from the Pontificia Universidad Católica de Valparaíso and holds a PhD in Science, specialising in Neuroscience, from the Universidad de Valparaíso. He undertook post-doctorate research at the Valparaíso Interdisciplinary Neuroscience Centre and is currently an associate researcher there. He works as an associate professor at the School of Medicine at the Universidad de Valparaíso and is a professor on the Medicine and Medical Technology courses at the Universidad de Valparaíso. He is also a member of the teaching staff of the Neuroscience and Cellular and Molecular Biology Master’s programmes as well as the Doctorate programmes in Neuroscience and in Health Sciences and Engineering at the Universidad de Valparaíso. He conducts basic preclinical research in the field of ageing and his primary line of research is aimed at understanding the molecular mechanisms associated with neurodegenerative synaptopathies such as Alzheimer’s disease.
