Plastics often get a bad rap – but Dr. Lewis Blackman from the CSIRO is here to convince you that while many are catastrophic for our environment, there’s also a whole world of “good plastics” out there! Clever plastics that can help save children from cancer, allow amputees to walk and as weapons to kill superbugs. This talk ventures into the nanoworld to focus on how smart, shape-changing, nanosized plastic vehicles can allow us to tackle some of the world’s nastiest diseases more effectively and with fewer side effects than ever before! Bio: Lewis is a Londoner who fancied a change from the Big Smoke to the Land Down Under. After spending a year teaching science in Ulaanbaatar, Mongolia, he completed a PhD in polymer chemistry at the University of Warwick. Lewis is currently a postdoctoral fellow at CSIRO working on developing new polymer biomaterials to combat microbial infections.
