or consulted as a professional in her field with her contributions clearly ascribed to her with her full name and designation tagged on?

unless that's happening she's dealing with a bunch of hacks and needs to make it clear that her name must be used, especially if the info used is from her thesis or similar.

decide her field of writing expertise; read magazines/newspapers that accept that kind of content and understand their style. then submit articles for consideration to the editors or section editors (their contact details aren't top secret often in the magazine or easily accessible with a phonecall).

if she can write, yay. if she can't she might get called upon to be a consultant or similar.

be warned, most medical practitioners take home a helluva lot more than journalists.
