Animations & Interaction

The Leeds Beckett University website occasionally uses animations to page elements and animated gifs to add impact to pages. If you wish to stop them from playing for accessibility purposes or for personal preference then please see the guidance below. Please note that browsers sometimes change how they operate, so please refer to your browser help files to find their latest information.
How do I turn off animations?

Dr Cliffe Schreuders

Reader

Dr Z. Cliffe Schreuders is Reader in Cyber Security and Director of the Cybercrime and Security Innovation Centre (CSI Centre) at Leeds Beckett University. He enjoys designing and programming novel solutions to challenging problems.

Cliffe completed his PhD in Computer Security at Murdoch University in Perth, Western Australia. There he gained experience teaching a wide range of subjects including computer security, software development, Linux / Unix system administration and security, IT project management and digital collaboration, and web development. Cliffe also spent time in industry working as a software engineer.

Since joining Leeds Beckett University, UK, he has had a pivotal role in developing cyber security curriculum with an emphasis on hands-on application of theory through experiential, problem-based labs. Cliffe leads the development of software and infrastructure that generates and hosts security challenges is at the heart of the curriculum. Cliffe also contributed to the NCSC accreditation of LBU cyber security degrees. Cliffe has led many successful research grants and founded the CSI research centre. Cliffe has specialist knowledge in cyber security, and is an avid proponent of Linux, free and open source software (FOSS), and free culture.
