Oscar Acosta is since 2010 an associate professor at the Signal and Image Processing Laboratory (LTSI - INSERM 1099)  in the ISTIC-University of Rennes 1, France. He was awarded a Bachelors degree in Electrical Engineering in 1995 and subsequently a Master of Sciences degree in 1997 by the University of Andes in Bogotá, Colombia. During his first degree, he undertook an internship at the Neuropsychological Department of the Military Hospital in Bogotá, working on an Alzheimer’s Disease project, specifically, developing and testing an eye-tracking device. In 1997, he proceeded to Brest, France for a seven–month internship with the LATIM-ENSTB Laboratory, where he worked on retina image registration. In 1999, he was awarded a PhD scholarship, under a cooperation program between European and Latin American Institutes (ALFA BETA Biomedical Engineering Training Action), which took him back to France, this time to the LTSI  at the University of Rennes I.  During his PhD he worked on the characterization of anatomical structures for the planning of vascular interventions. He worked as a research scientist in CSIRO in Australia between 2005 and 2009,  based first at Westmead Hospital in Sydney (where he undertook the segmentation of paediatric CT images) and then at the Australian e-Health Research Centre in Brisbane where the focus of his research was in medical image processing for the study of Alzheimer’s Disease as being part of the biomedical imaging team.   Between 2012 and 2016 he was member of the INSERM Scientific Specialized Commision  (CSS8-Technologies pour la Santé, Thérapeutiques, Biotechnologies). His main research activities are in image processing and computational methods for Prostate Cancer Radiotherapy in collaboration with the Centre Eugene Marquis.
