Dr. Nicolas Voelcker is Scientific Director of the Melbourne Centre for Nanofabrication, Professor at Monash University, and Science Leader at the CSIRO. He shares how applying his expertise in nanomaterials to anti-doping allowed him to work on exciting research projects and take advantage of great funding opportunities. He also describes the anti-doping testing applications of a porous silicon nanomaterial he works on, and how this material is used with mass spectrometry to detect prohibited substances.
