Dr Suelette Dreyfus, Academic Specialist, School of Computing and Information Systems, University of Melbourne

Dr Suelette Dreyfus is a Lecturer in the School of Computing and Information Systems at The University of Melbourne. She did her bachelor’s degree at Columbia University (Barnard College) in New York and her Ph.D. at Monash University. She is a frequent public commentator in the media on IT-related topics. Her main research areas are: cyber security and hacking, digital privacy and anonymity, the impact of technology on integrity systems (whistleblowing) and social media as a tool for language learning in schools. She wrote Underground, the first mainstream book about computer hacking in Australia, with Julian Assange, which was subsequently made into two different films and translated into seven other languages. Rolling Stone Magazine described the work as ‘entirely original’, and the book has become a cult classic.

For her research work on the impact of digital technologies on whistleblowing, she has been invited to appear before several parliamentary committees at a state and federal level in Australia. She has co-authored several international reports and papers in this area. She works with civil society not-for-profit NGOs internationally which seek to improve the whistleblower protection structures in their society, both in law and via use of technology. She has integrated these two research areas by co-developing an experimental programme to teach journalists how to protect their whistleblower sources by improving data security and anonymity.

Her e-education research work is in the use of social media for education. She initiated an innovative cross disciplinary project using social media to teach Chinese to Australian primary school children in Australia, and English to Chinese students in China. Prior to earning her PhD and entering academia, she trained and worked as a staff journalist on a major daily newspaper in Australia. Suelette is particularly enthusiastic about encouraging and supporting women in IT.
