About me

My name is David Llewellyn-Jones and I'm Reader in Computer Security at Liverpool John Moores University in the School of Computing and Mathematical Sciences. I'm working on various projects relating to security, secure component composition, networks and graphics, amongst others. For more info about this, take a look at my research pages.

David Before moving to Liverpool I worked for Codemasters programming computer games for about a year and a half. I helped in the production of TOCA/Pro/DTM Race Driver (the name depended on the SKU), a fantastic touring-cars-racing type game that was released for PC, PS2 and Xbox. I worked on the UI, game logic, audio and networking code.

Prior to this I completed my PhD at the University of Birmingham, researching under Richard Kaye in mathematical Model Theory.

Joanna The subject of my thesis was a mathematical structure known as Presburger arithmetic (or Z-Groups as they are also called), which is effectively the 'addition' part of arithmetic. Although all of the models which I looked at contain the integers, they will also often have extra 'infinite' elements larger than any of the integers but which behave in similar ways. I looked especially at automorphisms of the models, which constitute mappings which go from a model to itself; in other words they rearrange the elements of the model whilst still preserving its essential properties. You can read more detail about this and get a copy of my thesis from the maths pages.

Apart from maths I also enjoy programming, graphics and art. For computer related things have a look at my computer pages. I like to combine my interests, for example developing the Functy application for generating mathematically defined 3D images. Recently I've also been really taken by 3D printing, and you can print your own copies of my designs from my Shapeways shop.

Last, but certainly not least, the love of my life is my beautiful wife Joanna. We got married at in the year 2000 and you can see how lovely she is in the photo on the left.

Joanna and I live together in Liverpool, an exciting and historic city. Liverpool was European City of Culture in 2008. We live in Kirkdale a few miles north west of the city centre in a flat that's part converted from the old BAT Tobacco Wharf building.
