I started my working life in the BBC Scotland newsroom back in 1991.

After a few years of feeding the ever-hungry news machine, I decided that current affairs was where I really belonged.
I've always been pretty nosey and I've never been one to let something drop without a bit of a fuss. So, making half-hour films for Frontline Scotland seemed like the perfect place for me to cut my investigative teeth.
I was a reporter on Frontline for five years and, in that time my colleagues and I worked on some cracking stories. We went around the world, for example, investigating the case against the two Libyans who were then accused of the Lockerbie bombing.
On another assignment, we travelled the length and breadth of Pakistan to track down two girls from Glasgow who had been abducted by their father and forced into marriage.
One producer even managed to persuade me to pretend on the internet to be a 13-year-old girl named JoJo in an investigation into paedophilia. It brought results worryingly quickly.
A child molester befriended me and was later sentenced to 20 years in a Texan prison. After making 50 programmes, though, it was time for a change.
I moved to Panorama three years ago and have been able to continue reporting on subjects that I hope have made a difference. I have revealed a catalogue of errors in Britain's oldest branch of forensic science, fingerprinting.
Over the course of two years, in Finger of Suspicion then in Fingerprints on Trial, I followed the case of Bolton businessman, Alan McNamara, who was convicted of burglary on the basis of a single flawed fingerprint identification. He has since been granted leave to appeal against his conviction.
In The Tranquilliser Trap, the team and I revealed that a million and a half people in Britain are hooked on prescription tranquillisers - a situation the government's Mental Health Csar admitted was a "disaster". The BBC Helpline took 14,000 calls after that programme.
The government is now reviewing the way tranquillisers are prescribed and is expected to put them in the same class as methadone.
More recently, though, we have discovered that history is repeating itself with the mass prescription of newer, supposedly non-addictive anti-depressants like Seroxat.
Over the course of two investigations, we have discovered that many people who took Seroxat in the belief they could stop the drug whenever they wanted have, in fact, become hooked on it.
After the first programme was broadcast - and the drug's manufacturer read the 1,500 emails written by our viewers - the patient information leaflet was rewritten to drop the claim that "You cannot become addicted to Seroxat".
We also investigated claims that Seroxat could prompt disturbed behaviour and suicidal thoughts in some people who take it. In particular, we presented evidence that some children have become suicidal or self-harmed on the drug.
Shortly after we broadcast these claims the Medicines Regulator ruled that Seroxat should not be prescribed to under-18s. A special committee is currently examining all the safety concerns about Seroxat and other similar anti-depressants.
The work can be all-consuming but it's always rewarding, particularly now that the Panorama website brings us so much feedback from viewers. I spend my time away from work at home in Glasgow where I live with my husband.
