What we plan for our future career often changes as we are exposed to new things. As a teenager, Chris Arridge wanted to design computer games, but now he researches the invisible magnetic shields - the magnetospheres, that surrounds and protects planets.
We often think of outer space as a vacuum, but in fact there are lots of atoms, molecules and charged particles in space, and they can be measured by spacecraft and seen by telescopes. These particles are more concentrated around planets with magnetic fields, and form what are called magnetospheres. We live within the Earth's magnetosphere and it provides a protective shield, but can also be a danger, since storms can happen within it, causing a hazard to astronauts, satellites and terrestrial communications. My research uses data collected by instruments on spacecraft to understand the behaviour of magnetospheres and to help solve some of the problems they cause.
I originally wanted to be a computer games software engineer. I left school at 16 and went to a further education college to study computing. The course didn't allow me to go to university so I had to go back to college to pick up A-level mathematics. I did physics as an additional A-level and decided to change to the subject - applying for courses with a strong component in astrophysics, space science and planetary science. I got a place at the University of Wales, Aberystwyth, including a European exchange to Svalbard in the Arctic Circle, spending months studying the polar atmosphere, the northern lights, and space science.. I also applied for and got a summer placement at the Anglo-Australian Observatory in Sydney, Australia. Whilst on this placement I heard about a mathematics course run by Cambridge University. After my degree, I spent nine months on the course, studying general relativity, astrophysics, and applied mathematics. I rapidly realised that I enjoyed exploring the planets most of all, and applied for PhD places in this area, receiving an offer to work on the planet Saturn at Imperial College, using data from the Cassini mission, which was due to arrive at the planet during the first year of my PhD. Though I failed the course of mathematics at Cambridge, I started the PhD, completing it just over three years later.
Many people and experiences inspired me to become a researcher. My parents took me to a planetarium in summer holidays, and I used to watch a TV programme called Cosmos, with Mum. Dad, was an engineer, and sometimes took me with him to work. My summer placement in Australia had a big effect on me, and an A-level tutor inspired me greatly through introducing me to what it meant to be a scientist.
I love the moments when you realise you have found out something that no-one else in the world knows yet. They don't come around every day, but when they do it is a powerful feeling. I enjoy being part of a worldwide community. People of all ages and backgrounds do science. Although research can be quite blue skies, there are applications in all sorts of unexpected areas and new fields.
