After starting professional life as a newspaper journalist in her native Dundee, Susan was working as a reporter for BBC Radio Aberdeen when she was invited to join the presentation team in London.
After three years there, she embarked on a broadcasting career which lurched along entirely due to serendipity. A stint on You and Yours was followed by some years of TV presentation.
Over the last few years, Susan has become a regular voice on many TV channels as a narrator of countless documentaries. One side effect of this is that she can bore for Scotland on virtually any topic - forensic medicine, dinosaurs, rare diseases and so much more. But she found herself missing the call of live radio, and started presenting for BBC World Service a couple of years ago.
From there, it was back to Radio 4 and Radio 4 Extra.
