Professor Ryan Ko is Chair and Director of UQ Cyber Security at the University of Queensland, Australia. His applied research in cyber security focuses on 'returning control of data to cloud computing users'. His research reduces users' reliance on trusting third-parties and focusses on (1) provenance logging and reconstruction, traceability and (2) privacy-preserving data processing (homomorphic encryption). Both his research foci are recognised nationally and internationally, receiving conference Best Paper Awards (2011, 2015, 2017), and technology transfers locally and internationally.
