The sixth episode focuses on the very specific role of a data manager within interdisciplinary communication in clinical research projects. It features Mr. Tomas Machulka who is now affiliated with Premier Research as an associated manager for clinical data sciences. He serves also as a senior consultant for CZECRIN - the Czech part of the European Clinical Research Infrastructure Network.  Let's listen to some of his experience with risk-based quality management and queries. Let's get inspired by someone who is able to recognize the importance of an EDC system in a tech ecosystem used by data managers. Who is telling the truth? Feel free to ask your data manager, who has the role of a criminal detective!
