In episode 23 we chat with Dr. Simon Baunwall, a medical doctor and scientific researcher focused on fecal microbiota transplantation, also known as FMT. Dr. Baunwall is based at Arras University Hospital in Denmark.

This conversation centred around the establishment of fecal microbiota transplantation (FMT) as a therapy in Denmark.

Simon talked to us about his work which centres around establishing FMT as a standardised, scalable approach using a blood banking type model, is fascinating. We talked about his perspectives on how the field might evolve looking forward, the next indication after recurring C-difficile infection, and the progression of FMT delivered by colonoscopy to delivery by capsules.

And we had some interesting philosophical discussions around what is the mechanism of action and how do you define a dose. This is important, as historically what researchers have used is the wet mass of starting material, in other words, stool, that goes into the process. But what we discussed is actually, that's probably not a good definition or metric for dose!

Additionally, we talked about the regulations, which Simon's been very heavily involved with. I particularly enjoyed this episode because Simon is a self-confessed lover of the Inside Matters podcast.

In fact, he has listened to pretty much all the episodes. So it was amazing to have a loyal listener on the podcast to talk about their fantastic work in the microbiome and FMT space.
