Charles Weijer is Professor in the Departments of Philosophy and Medicine, and Canada Research Chair in Bioethics at Western University in London, Canada. His academic interests centre on the ethics of medical research. Publications on the use of placebos in clinical trials, weighing the benefits and harms of research, and protecting communities have been broadly influential. From 2007–2012 he co-led a collaboration that produced the first international ethics guidelines for cluster randomized trials. He is currently collaborating with Adrian M. Owen on a project exploring the ethics of functional neuroimaging after severe brain injury. He has received a number of honors for his research, including Western's Hellmuth Prize for Achievement in Research (2014). In 2008, he co-founded the Rotman Institute of Philosophy (rotman.uwo.ca), which is dedicated to fostering collaboration between the humanities and the sciences, and served as the Institute's first director.
