Professor Perdita Barran is Chair of Mass Spectrometry at Manchester University and is part of a team working to identify biomarkers in our smells that can help diagnose conditions - including Parkinson’s and some cancers.
Perdita joins Jim to discuss how a woman who can sniff out people with Parkinson’s disease has been a catalyst for the research and where it’s headed now.
