I have never understood the use of «Dr» for people that are not medical doctors.
It's quite normal in the UK, though I suspect most people with a DPhil only ever use the title 'Dr' in formal or academic settings. This kind of publication is one of those, BUT they'd usually state the person's area of expertise as well. It rarely seems to cause much confusion.
«Katrina Pears, PhD» is a US format, which I'm not sure I've ever seen in Britain.
