Staff Profile

I am a senior lecturer in Cyber Security at Newcastle University as of the 1st of September 2022. I am the director of the MSc in Cyber Security and a member of the PhD progression panel.

Prior to joining Newcastle University, I was a senior lecturer at UWE Bristol. Prior to that, I worked with Prof Jens Groth as a research associate in the Information Security Group at University College London from 2015 to 2017. Prior to that, I was at the Computer Science Department at the University of Bristol between 2011 and 2015 as a post-doctoral researcher in the Cryptography Group and then as a teaching associate.

I obtained my PhD in Computer Science from the University of Bristol working on Cryptography & Information Security in 2012. My supervisors were: Prof Nigel Smart and Dr Bogdan Warinschi​.

I got my Master's (with Distinction) from the University of Bristol in 2007 and my MSc project on multi-authority key-agreement protocols won the best advanced MSc project in security award. 

Between obtaining my first degree and starting my Master's, I have worked for a number of years as a Programmer & System Analyst.

I am interested in various aspects of Cyber Security, and in particular Cryptography & Information Security. For more about my research, you can refer to my Google Scholar profile: https://scholar.google.com/citations?user=PGzWWUUAAAAJ&hl=en .

Example of past/recent topics/projects include, but not limited to:

• Digital Cash
• Structure-Preserving Cryptography
• Direct Anonymous Attestation
• Attribute-Based Cryptography
• Proof systems and their applications
• Signature schemes and related primitives (e.g. blind signatures, Group Signatures, Ring Signatures, etc.)
• Public-Key Encryption
• Post-Quantum Security 
• Blockchains
• Adversarial & Privacy-Preserving Machine Learning 

Note to potential PhD applicants:

While I am always keen and eager to supervise highly-motivated and hard-working PhD students, I will not be able to check and comment on CVs and other documents sent by email. The best way to approach me in this regard is to first ensure that your suggested topic/interest/proposal aligns with my research interests. Therefore, you should include a brief a personal statement summarising how you think our interests align and providing details of how you think you have the required background, e.g. what relevant courses have you studied or what projects you have worked on which are relevant to the proposal/topic you would like to pursue for your PhD. Please note that any funded studentships I have will be advertised publicly on the university portal and other known public channels.

Note: Any available funded opportunities (for a PhD or a post-doc) will be advertised through the university website and highlighted here. Currently, I do not have any funded opportunities unless they are officially announced on the university website.
