As part of BEBPA’s mandate to provide forums to foster scientific discussion among biopharmaceutical scientists, we actively write up the results of these discussions. These written updates come in the form of White papers written by a committee of scientists, the results of live interactive surveys and occasionally written reports by attendees. These reports are made available to the public and can be downloaded freely.
