I'd like to know where you got that from because her PhD is in physics.

It's not often that media studies graduates go on to do a physics doctorate!

We can see from this link that she has a BA (Hons) degree in physics from Bristol University, followed by a PhD in physics.
Check your facts - surely that's what a good scientist would do! - and be an example to her.
