The conference papers demonstrate well the challenges big data offer today for biomedical informatics - to connect molecular and cellular biology to the clinical world allowing us to consider individual variations and not simply population averages. But, with big data we need to take into account the security and privacy requirements for personal health data which means that data users should be accountable for the custodianship of personal medical information.
This will be a challenge as we are dealing with both regulated and non-regulated healthcare environments and with reuse of data and secondary use of health data.
