Bio: International engagement is essential to conduct science, develop infrastructure, and train the next generation of scientists and engineers. In 2002, Peter Arzberger, Philip Papadopoulos, and leaders from more than ten institutions helped establish the Pacific Rim Application and Grid Middleware Assembly (PRAGMA), which is supported in part by the National Science Foundation (NSF). PRAGMA\'s goal is to build sustained collaborations between researchers around the Pacific Rim by building applications on top of the emerging grid hardware and software (www.pragma-grid.net). PRAGMA consists of more than 30 institutions around the Pacific Rim. We are focused on testing and deploying cloud-like serves to enable applications. I serve as Chair of the PRAGMA Steering Committee.

Multidisciplinary research is increasingly important to address major societal problems in, for example, health and the environment. Arzberger is the Director of the National Biomedical Computation Resources (NBCR), funded by the NIH National Center for Research Resource (NCRR). NBCR investigators include leading researchers from multiple departments and institutions. NBCR conducts, catalyzes, and enables biomedical research by harnessing forefront computational and information technologies to solve multiscale analysis challenges in basic and translational science. Its focus is on developing tools, simulation packages and flexible cyberinfrastructure, and NBCR researchers are driven by three interdisciplinary biomedical applications: patient-specific modeling in cardiovascular disease; mesoscale subcellular imaging and modeling tools; developing a computer aided drug discovery pipeline. NBCR\'s annual Summer Institute involves hands-on training to facilitate using the tools and to better understand and collaborate with the community of users.

In 2004, Arzberger helped initiate the Pacific Rim Experiences for Undergraduates (PRIME) program, which provides opportunities for UCSD undergraduates to conduct an internship at a PRAGMA site, creating experiential research and cultural awareness learning. PRIME was initiated with funding from NSF, and additional support from Calit2. Currently PRIME sends students to seven sites around the Pacific Rim. Two other programs have been developed by PRAGMA partners that allow students from other sites to work in the United States: the Monash University Research Abroad Program (MURPA) and the Pacific Rim International Universities (PRIUS) at Osaka University.

Another outgrowth of PRAGMA, based on the EcoGrid activity of the National Center for High-performance Computing (NCHC) in Taiwan, is the Global Lake Ecological Observatory Network (GLEON). This organization currently involves institutions around the world, and focuses on establishing a research, collaboration, and data framework to conduct network science. With funding from the Moore Foundation and the NSF, steps will be taken to extend this network to more lakes around the world, to harden software to build strong local data streaming infrastructure, and to gain a better understanding of the role of lakes in the carbon cycle.

Peter Arzberger has served at the NSF in various roles: Program Officer in the Mathematical and later Biological Sciences; Division Director of the Division of Biological Infrastructure; acting Assistant Director and then advisor in the Directorate for Computer and Information Sciences. \"I highly recommend serving at NSF to gain a better understanding of science and to help contribute back to our community,\" says Arzberger.

He has also been a member and later chair of the U.S. Long-Term Ecological Research (LTER) network National Advisory Board, and previously served as Executive Director of the San Diego Supercomputer Center (SDSC) and the National Partnership for Advanced Computational Infrastructure (NPACI).
