Physics

My research interests centre around model building using extra dimensions, and the phenomenology of such models at the electroweak scale as is relevant for their testing at the Large Hadron Collider (LHC). In this area my current work looks at the phenomenology of soft-wall models, as well as truncated Randall-Sundrum (RS) spaces with brane localised scalar curvature terms. I also have a separate interest in using the method of Lie-point symmetries, in combination with model building, to obtain an exhaustive list of possible relationships between parameters for a given Lagrangian, in order to aid in understanding and extending the standard model.

Micro Python

At the end of 2013 I ran a Kickstarter campaign for the Micro Python project, which is a lean and fast implementation of the Python programming language that is optimised to run on microcontrollers.

The official page for Micro Python is micropython.org. This page has minimal information on it at the moment and will be updated in the coming months. It includes a form to sign-up to buy a board.


Web sites

Check out thecmb.org for a visualisation of the latest Planck data.

Paperscape is an online tool used for visualising and managing papers from the ever-expanding arXiv. Rob Knegjens and I are developing it as a side project.


Robotics

I studied robotics as part of my undergraduate degree. This included participating in Robocup 2002, an international robotics competition where teams program robots to autonomously play soccer against each other. Our team came in 4th place, out of 19 teams. There are some photos of the competition.

The paper that resulted from my Robocup work:

  • D. George, N. Barnes, Particle Attraction Localisation,
    Proc. IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS2003), Las Vegas, USA, Nov., 2003, (PDF)

I built a simple walking robot that can follow a blue light.

I have designed and built a fully working CNC machine.
