A wealth of new and advancing technologies are changing the way we approach research in healthcare. The use of big data sets, precision medicine and machine learning mean that research studies can be bigger, cheaper and wider reaching than ever before. In this lecture, Professor Martin Landray, Deputy Director of the Big Data Institute, and Professor of Medicine and Epidemiology at the University of Oxford, will consider how recent advancements in healthcare technologies have radically changed how we go about medical research, and look at how future innovations could further shape the field.
