    I am in full time higher education (University) studying for a Masters (Hons.) in Physics with Particle Physics and Cosmology. Such a subject requires me to have a wide range of skills, good time management and the ability to logically approach tasks given to me. Over the past several years, I have worked on the occasional project developing my skills in basic programming, and web design; which equates to approximately two years of professional experience. Two years prior to University, I taught myself the LaTeX typesetting language; know it was the industry standard for typesetting Physics, Engineering and Mathematical documents. Since then, my skills in LaTeX have grown to include AMS-LaTeX equations and BibTeX referencing. More recently I have extended my skills further to included being able to write basic custom packages and classes. I have used Windows, Linux and Mac operating systems and comfortable on all three. I look forward to gaining more professional experience, improving myself and my skills, and your company.  less
