Roberto Barrera – impressive set of contributions John Delaney – persuaded you that you should all start working on ocean observation I have worked for many years with some incredible people in the physical sciences, working to understand some fascinating phenomena, such as the nature of mass and the causes and likely effects of climate change. These people have been the early leaders in developing and applying grid technology, via such projects as the LHC Computing Grid and the Earth System Grid. Jonathan: 1) Evidence-based medicine is use of carefully evaluating the results (called outcomes) of different diagnostic or therapeutic procedures to determine the best choice for a population of patients. Then a physician, with this information at his/her disposal (a complicated problem to have that happen in itself) can make the best decision for the individual patient by looking at the characteristics of the studied patients and his/her own patient (N of 1) and can make recommendations (patients, not doctors, make choices) 2. personalized medicine (in a nutshell here - purists might disagree) is2:58using much finer distinguishing characteristics to do the same thing such as specific genomic studies that ensure that the N of one patient is precisely matched with the same sub-sub-sub population of patients2:59Thus, the distinction at some level, blurs, when we have enough examples of personalized medicine (it becomes the evidence-based medicine of the future) but for now all we have is evidence-based medicine (a much more blunt instrument) with the same goal

To realize the promise of quantitative medicine, we must break down barriers to information sharing … Discovering effective personalized treatments Determining the right treatment for the individual … and deliver new analytical tools to make sense of large quantities of data
Why it is hard?
A large, dispersed community
Huge quantities of data
Great diversity of data
Inadequate computing capabilities
Lack of a culture of sharing
Privacy concerns
Basic Research Clinical Practice Clinical Trials trial subjects, outcomes library Outcomes, tissue bank screening tests ongoing investigative studies pathways
Healthcare and infrastructure
Increased recognition that information systems and data understanding are limiting factor
… much of the promise associated with health IT requires high levels of adoption … and high levels of use of interoperable systems (in which information can be exchanged across unrelated systems) ….
RAND COMPARE
Health system is complex, adaptive system
There is no single point(s) of control. System behaviors are often unpredictable and uncontrollable, and no one is “in charge.”
W Rouse, NAE Bridge
Need to blur boundary from research to clinical
… I advocate … a model of virtual integration rather than true vertical integration….

Schizophrenia as a neuropsychiatric model (Potkin, UCI)
A brain illness with subtle structural and functional changes
Active area of imaging research with many competing theories and approaches
Progress hampered by
Inconsistent data & lack of replications
Noncomparable imaging techniques
Small, diverse patient populations

Lessons learned from BIRN (G. Farber)
There is little point in sharing data unless there is community agreement on how to standardize data collection
There continues to be a communications/ease of use gap between computer scientists and biomedical researchers
Sharing heterogeneous data from biomedical experiments is a challenge to existing data sharing infrastructures
Complex queries are a really hard problem
