Lisette Sibbons - graduated 2005

Lisette Sibbons What is the subject of your PhD?

I am studying old- and intermediate-age stars in Local Group dwarf galaxies. Specifically, I am interested in the ratio between carbon-rich and oxygen-rich AGB stars. This ratio measures the abundance of iron in the environment where these stars formed and so helps us to trace the chemical enrichment and evolutionary history of the galaxy. Understanding the history of dwarf galaxies is particularly important as they can help us to understand the formation of larger galaxies in a cosmological context.

What is the best thing about doing a PhD?

The best thing about doing a Ph.D. is the exposure to a wide range of research and developing ideas at the forefront of modern astrophysics. Seminars, guest speakers and conferences have all given me the chance to learn about other areas of research outside my own field and to get a better idea of the 'big picture'. I have also very much enjoyed developing my project as my understanding and confidence with the subject of my Ph.D. has grown.

How did you find your PhD place?

I identified all the universities in the UK that were offering Ph.D. places. I was particularly interested in working on resolved stars in the Galaxy or Local Group so I applied to all of the universities that were offering projects in that area. This is how I got my place at the University of Hertfordshire. I also found potential PhD place in the UK and abroad through the Royal Astronomical Society mailing list.

How is your PhD place funded?

My PhD is funded by the Science and Technology Facilities Council (STFC) - this includes my university fees and a stipend for living expenses during my PhD.

What would be your advice for current students who are thinking about doing a PhD?

I would advise anybody that is considering doing a Ph.D. to start reading short academic papers as soon as possible. These can be overwhelming at first but it will show you the breadth of research that is currently being done and how it is being done. It will also help you to identify the areas in which you interested and help familiarise you with the terminology and style of academic papers, which are likely to be a big part of your Ph.D. There is quite a big transition from a taught course to independent research and reading about the work done by others is a big part of this if you can start this process early it will help you in your work and probably in the interview process as well.
