Her system Pegasus, funded by SI2/SSI, is used in a number of scientific domains to automate large-scale application execution on distributed, heterogeneous resources. LIGO uses it for the analysis that confirmed the existence of gravitational waves.
Expert in resource provisioning, monitoring, adaptation, and performance analysis of scientific workflows on distributed, networked cloud platforms. He has also worked on anomaly detection for scientific workflows on networked clouds, scheduling scientific workflows based on performance models, and fault-tolerance for science workflows. He contributed to many elements of the NSF GENI effort: development of provisioning and control software for ExoGENI, core development in ORCA/ExoGENI for supporting dynamic modification for slices, GENI monitoring infrastructure, and evaluating domain science workflows on GENI.
Expert in cyberinfrastructure development. He has collaborated with a broad range of scientific communities, such as astrophysics, polar and environmental sciences, physics, biomedical sciences, engineering, social sciences and the humanities. Nabrzyski has experience in evaluating third party infrastructures, and has been involved in testing and evaluation activities for IARPA programs. Led by Nabrzyski, Center for Research Computing (CRC) is a team of 55 social scientists and experts in cyberinfrastructure development, open data, sensor and drone technologiess. Nabrzyski was a co-PI on the NSF funded EarthCube Polar-Cyberinfrastructure RCN.
Expert in data management and analytics methods for Big Data with leadership positions in several national and international efforts. He has developed several techniques for massive data storage and streaming integrated with analysis and visualization algorithms that scale from handheld or web-based platforms to massively parallel supercomputers. His work has targeted a variety of collaborative applications in neuroscience, climate and weather modeling, clean and efficient energy production, materials science, medicine, subsurface modeling, precision agriculture, among others. Pascucci is the founding director of the Center for Extreme Data Management Analysis and Visualization and has lead the development of data streaming solutions in a number of projects.
Expert in designing, building, and operating research infrastructure. He leads the NSF-funded CloudLab facility, which serves thousands of researchers working on infrastructures for cloud computing. CloudLab collaborates with other infrastructure projects which use its facilities as a way of testing improvements on their own infrastructure: these projects include the CyVerse MREFC project and members of the LHC team. Dr. Ricci has also lead the Apt NSF MRI, is co-PI of the NSF-funded Emulab Powder, and PhantomNet testbed facilities, and played a major role in GEN. He is co-director of the Flux Research Group that conducts research (in computer systems and networking) and builds research infrastructure. The group has three dozen members, include 8 full-time research staff.
Computer scientist in the Science Automation Technologies group at the USC Information Sciences Institute. He is currently involved in several national cyberinfrastructure deployments such as the Open Science Grid and XSEDE, for which he provides user support, software engineering and system administration. Previously, he was at the Renaissance Computing institute where he was the technical lead on the RENCI Science TeraGrid Gateway and the Open Science Grid Engagement activities. Before that he was a release manager on the NPACI NPACKage and NSF Middleware Initiative projects where he planned, created, and tested software middleware stacks for larger science communities.He also worked on improving grid software as part of Community Driven Improvement of Globus Software (CDIGS) and Coordinated TeraGrid Software and Services (CTSS) efforts.
Expert in networking technologies. He is responsible for developing and deploying the ExoGENI edge cloud system - part of the GENI federation of testbeds funded by NSF. The ExoGENI effort included developing and maintaining the control framework software, deploying and maintaining the hardware at 20+ ExoGENI sites around the world. He maintains expertise in and collaborates with a variety of networking/distributed CI projects: GENI, NSF Clouds, PRP/NRP, Internet2, and ESnet. He is a lead author of the vision paper for the future CISE mid-scale infrastructure.
Wyngaard is an Mechatronics Engineer with a passion for open source technologies that enable the Sciences. She holds an undergraduate degree in Mechatronics Engineering from the University of Cape Town South Africa, where she also completed her Doctorate focused on microprocessor design for Scientific High Performance Computing. Following a post-doctoral position building BigData tools for Earth Science at the NASA Jet Propulsion Laboratory, she joined the University of Notre Dame's Center for Research Computing as a computational scientist. Here she is pursuing her research interests in building embedded open source hardware and software tools for Science applications including; using Remotely Piloted Aircraft Systems and connected Edge Computing for data capture, Data analytics and Management on Embedded Systems, and connecting High Performance Computing resources to limited resource edge devices.
