2. “The Heavy Red Bag” How can computers advance (my) science?

4. A new collaborative scientific initiative at Harvard.

5. Computational challenges are common across scientific disciplines How to: Acquire, transmit, organize, and query new kinds of data? Apply distributed computing resources to solve complex problems? Derive meaningful insight from large datasets? Share, integrate and analyze knowledge across geographically dispersed researchers? Visually represent scientific results so as to maximize understanding? Opportunity to collaborate and apply insights from one field to another

6. Filling the “Gap” between Science and Computer Science Increasingly, core problems in science require computational solution Typically hire/“home grow” computationalists, but often lack the expertise or funding to go beyond the immediate pressing need Focused on finding elegant solutions to basic computer science challenges Often see specific, “applied” problems as outside their interests Scientific disciplines Computer Science departments

12. New technologies for measurement and simulation are transforming the “workflow.” Manual/low throughput Solitary Limited by two hands Analog High throughput Automated/networked Highly scalable Digital Biomedicine: pre-genomics Biomedicine: genomics era

13. Continuum “Pure” Discipline Science (e.g. Galileo) “Pure” Computer Science (e.g. Turing) “Computational Science” Missing at Most Universities

14. Workflow & Continuum For any particular scientific investigation: Where does, and could, “computational science” make improvements in this cycle?

15. Harvard Public Health “NOW” (Oct. 2004) "In the past, experiments did not involve such large data sets," observed Dyann Wirth, professor of infectious diseases in the Department of Immunology and Infectious Diseases and member of the advisory group for the core. "There has been a dramatic change in the past five to 10 years in the amount and availability of genomic data [or the DNA sequences themselves] and functional genomic data, [or the sequences’ purpose]." In the past five years alone, the genomes of humans, rats, and the malaria parasite Plasmodium Falciparum have been published, for example. Dyann Wirth "One of the purposes of bioinformatics is to reduce the number of experiments that need to be done to achieve reliable information," said L.J. Wei, professor of biostatistics in the Department of Biostatistics and member of the advisory group for the core. "However, an issue right now is that there are huge data sets that can be run through different kinds of software programs, ending up with many data points. Unless we understand and use bioinformatics well, we may not even know which of those data points are important." L.J. Wei

16. Filling the “computational science” gap: IIC Problem-driven approach …focusing effort on solving problems that will have greatest impact & educational value Collaborative projects …combining disciplinary knowledge with computer science expertise Interdisciplinary effort …to ensure that best practices are shared across fields and that new tools and methodologies will be broadly applicable Links with industry …to draw on and learn from experience in applied computation Institutional funding …to ensure effort is directed towards key needs and not driven solely by narrow priorities of funding agencies

55. IIC: Mission The Institute for Innovative Computing (IIC) will make Harvard a world leader in the innovative and creative use of computational resources to address forefront scientific problems. We will focus on developing capabilities that are applicable to multiple disciplines, by undertaking specific, well-defined projects, thereby developing tools and approaches that can be generalized and shared. We will foster the flow of ideas and inventions along the continuum from basic science to scientific computation to computational science to computer science. We will train a next generation of creative and computationally capable scientists, build linkages to industry, and communicate with the public at large.
