I am currently studying for a PhD in Cyber Security at the University of Oxford, specifically focusing on privacy and Internet-of-Things devices. In 2015, I completed my Centre for Doctoral Training (CDT) year in which I studied the area from a multidisciplinary approach. These modules specialised in security architectures, ethics, data analysis, human factors, criminology, digital forensics and international relations. I received a 79% average across the topics, being ranked second-highest in the 15-person cohort. Since then I have been researching privacy and the IoT, having several papers published at reputable journals/conferences. I am also a reviewer for the Journal of Information Security and Applications and the Security and Communication Networks journal. I am due to graduate from Oxford in September 2018, and am considering both academic and industrial roles.

I have also led the Computer Security and Advanced Security (MSc) practicals: the former specialising in linear and differential cryptanalysis, and the latter concerning steganography and homomorphic encryption. In addition to this, I tutored the Computer Security Major Tutorial for the Worcester College Visiting Student Programme. I am also a departmental Student Ambassador, a Computer Science author for the Oxplore initiative, and a member of the Equality and Diversity Committee (EDC). Alongside my studies, I am a member of Wolfson College, the Oxford Union, the Oxford International Relations Society and Cymdeithas Dafydd ap Gwilym (Oxford Welsh Society).

Prior to joining Oxford, I completed an MPhil with Distinction in Advanced Computer Science at Christ's College, University of Cambridge, researching Denial-of-Service attacks with Dr Robert N M Watson.

I received my undergraduate degree from Aberystwyth University in Wales, completing a First-Class BEng (Hons) in Software Engineering and developing a cryptographic application alongside Prof Reyer Zwiggelaar. I was awarded their Evan Morgan Scholarship for Computer Science in 2008.

Outside of academia, I have had software development roles in the financial and pharmaceutical sectors.
