Joshua Schumacher

Joshua Schumacher is a Process Engineer in the NanoFab Operations Group. He received a B.S. and a Ph.D. in Electrical Engineering from the University of South Florida (USF), where he also received a certificate in Materials Science. For his doctoral research, Joshua collaborated with the Moffitt Cancer Center, Tampa, where he worked on carbon nanotube (CNT) growth and developed a CNT-enhanced method for improving the detection and analysis of peptides at low-concentrations. Prior to joining the CNST, Joshua worked on materials characterization using scanning electron microscopy, transmission electron microscopy, and focused ion beam systems at the Nanotechnology Research and Education Center at USF. Joshua is responsible for training NanoFab users and for operating the NanoFab's focused ion beam systems.
