I think it's … the profession is starting to realise that in part it's the general climate, and the way we treat each other is not conducive for having more women in the profession. It's not just about promotion but it's about the general environment and how people talk to each other and address each other in seminars and things like that, that we need to work on a culture that is more respectful and that will be more acceptable for many women who think that they don't want to play the games of shouting at each other.

The next generation of telescopes will see millions of events per night with computers that sift through huge amounts of data. If we had had access to a computer, we would never have programmed it to look for something so unexpected. How do you pick up the things you don't know exist, the things you can't tell it to look for? My project was to study quasars, and then we accidentally stumble over these things called pulsars. They were totally unexpected, totally unknown – and it's been huge fun.
