The personal website of John Welford


Dr John Welford MEng PhD CEng MIET MINCOSE

I am a chartered mechatronics and systems engineer with a PhD and over 10 years engineering experience in the defence, automotive and rail industries. I am an active STEM ambassador, regularly giving talks and running activities in local schools and colleges. I also have a keen interest in visualisation and data presentation.

In my personal time I am a mountain biker and snowboarder, alongside numerous other small projects and distractions - some of which are mentioned on this site.

For further information please see my CV or contact me directly.
