Hi Allison,
I don't know if this is a silly suggestion, but as some of us are not located in the UK, where PPI is more developed, we have never experienced first-hand how PPI is applied in practice. Reading and videos are really helpful, but maybe if you could tell us like a "story", giving examples of your own experience, of how PPI was applied throughout a whole study or at different stages, it would be helpful in order to see the big picture and for sure, I would definitely remember your lively tutorials more than papers in the future 
Additionally, I would like to know your thoughts about what the future holds for PPI in Pharma. As regulatory authorities pose high demands in the design of studies that seek marketing authorisation and legal departments won't allow for information sheets and consent forms to be more "friendly" (which of course are becoming "booklets" given the experimental phase of the drugs), it is hard for me to imagine patients/public sitting at our meetings!
Anyway, just personal suggestions 
looking forward to tomorrow's lecture!
