Originally educated as a materials scientist, Paul has attained interdisciplinary experience in diverse areas such as experimental spinal cord surgery and clinical device fabrication. He performed his Ph.D. at the Lions Eye Institute in Perth, Australia, where he was part of a team taking an artificial cornea from concept to the clinic. His first post-doc was at the University of Toronto, Canada, with Molly Shoichet developing hydrogels for nerve regeneration while his second was conducted at Aachen University, Germany, with Martin Möller, applying nanotechnology to life science applications. Later, as a research fellow at the University of Southampton, he investigated neuroinflammatory profiles of hydrogel scaffolds implanted in the spinal cord. Between 2009 and 2011 he split his time between Shanghai Jiao Tong University in China and Queensland University of Technology in Australia to develop MEW. Paul has published over 100 research articles in journals that include Advanced Materials, Progress in Polymer Science and Nature Materials. He is currently a Professor at the University of Würzburg, Germany.
