What do you do in your job?

I investigate how galaxies and stars are born and change with time (evolve) from after the Big Bang to the present day. I do this by using very large maps of the way galaxies are spread out across the Universe and try to recreate this using computer models of galaxies.

I also work on new space missions, making the test plans to make sure that the cameras and detectors work as they should before and after launch into space. I have worked for the Japanese, Canadian and European (ESA) space agencies and am now doing this for a space mission to look for exoplanets (planets outside our Solar System) and a mission that will create a new 3D map of our own Galaxy, the Milky Way.

How does your work have an impact?

I could list the various techno-spins offs from space missions, but to be honest I think the biggest impact as astronomers is in inspiring and motivating the public and especially the younger generations to be proud of, and take up and study science whether it takes them to astronomy or elsewhere to engineering, biology or medicine.

What’s the best thing about your job?

Apart from following my childhood dream to study the Universe, astronomer is a GLOBAL job, we have to travel to loads of exotic places, meeting really interesting people and using telescopes atop volcanoes.

What did you study at school?

I studied a pretty broad set of subjects for GCSE at school but then Physics, Maths and Computer Science for A-Level.

What inspired you into a career in science/engineering?

From an early age I always wanted to be an astronaut but in that distant past it was impossible unless you were a military pilot (these days, for today’s children, it’s much easier to get into space!). Luckily, I was also amazed by space so I did the next best thing, and studied the Universe!

Chris’s top tips for a career in science

  • You have to have a passion for what you do
  • You have to be always enquiring and seeking solutions
  • You have to work at the maths
  • It helps to have a broad knowledge about the subject – I read around a lot
  • It helps to like Sci-Fi films!
