Dr Juan Varela
Research Fellow
Research areas
Juan Varela studied physics in Uruguay and did his PhD in Ireland at the Centre for Bio-Nano Interactions, University College Dublin. He subsequently did a postdoc at the Interdisciplinary Institute for Neurosciences in Bordeaux (France), and a second postdoc in neurodegeneration at the Department of Chemistry at the University of Cambridge (UK). Juan has recently established his research group at the University of St Andrews funded by a European Research Council Starting Grant. His main research interests are the use of nanotechnology and high resolution microscopy to understand and cure neurodegenerative diseases.
