John Zic is a Research Team and Science Leader for Trusted Systems in the CSIRO ICT Centre. He holds a Visiting Associate Professor position in the Schools of Computer Science and Engineering at UNSW. Prior to this position, he was Acting Research Director for the laboratory for two years. He has also held research positions at Motorola's Australian Research Centre from 1999 to 2003, has taught networking, advanced networking, and concurrent computing at undergraduate and postgraduate levels from 1982 to 1999 as lecturer in charge and tutor.

He has been involved in networking research, from ALOHA experiment days, through to the development of the first diffuse infrared wireless LAN and onto IPv6 and home networking research.

His research interest is in the application of design and modelling techniques to protocol verification, validation and analysis.
