Quitting teaching to return to academia

I've just quit the teacher training course I did for the last 6 months in Bristol. Being a secondary school maths teachers just isn't for me. I enjoyed it for months, but once the novelty wore off I realised that it required was too little maths and too much parenting.

I'd be happiest doing a PhD. I'm got enough qualifications and experience in maths and software development. I could return to full time employment also, but I want to investigate the PhD first.

Hopefully, my next blog post will be to announce a confirmed PhD and the research project. I've talked to a few academics and am now confident I'll be able to arrange a suitable project this year. I'm fairly flexible, but I want to make use of my software experience and my maths knowledge. Perhaps I might consider staying in academia permanently; perhaps it's better to work with, not in, industry. I just want to do some basic research, I suppose.

I did a Masters in High Performance Computing, so something involving parallel computing to study statistics might be the sort of thing.
