Selected Current Projects

  • Virtual Data Collaboratory (VDC)

    The Virtual Data Collaboratory (NSF Data Infrastructure Building Blocks) is a federated data cyberinfrastructure that is designed to drive data-intensive, interdisciplinary and collaborative research, and enable data-driven science and engineering discoveries. VDC accomplishes this by providing seamless access to data and tools to researchers, educators, and entrepreneurs across a broad range of disciplines and scientific domains as well as institutional and geographic boundaries. VDC is federated and coordinated across three geographically distributed Rutgers University campuses in New Jersey and multiple campuses in Pennsylvania and New York. Central to the VDC vision are three infrastructural innovations, a regional science data science DMZ network that provides services to enable efficient and transparent access to data and computing capabilities, an expandable and scalable architecture for data-centric infrastructure federation, and a data services layer to support research workflows that utilize cutting-edge semantic web technologies, support interdisciplinary research, expand access, and increase the impact of data-science. VDC builds on and integrates existing data repositories, including NSF-funded repositories (e.g., OOI), and has the potential to leverage national ACI investments and interoperate with multiple data repositories.

  • GeoSCIFramework

    This project develops a real-time processing system capable of handling a large mix of sensor observations. The focus of this system is automation of the detection of natural hazard events using machine learning, as the events are occurring. A four-organization collaboration (UNAVCO, University of Colorado, University of Oregon, and Rutgers University) develops a data framework for generalized real-time streaming analytics and machine learning for geoscience and hazards research. This work will support rapid analysis and understanding of data associated with hazardous events (earthquakes, volcanic eruptions, tsunamis). GeoSCIFramework proposes an innovative approach that looks at the world with a fly’s eye perspective where a composite of thousands of harmonized high-rate real-time GNSS, seismic, pressure and other sensors will continuously stream data into an integrated framework and combined with a background of satellite radar time series generated at a 100 meter pixel level across the globe and made available through XSEDE.

  • DyNamo

    Dynamo will allow atmospheric scientists and hydrologists to improve short- and long-term weather forecasts, and aid the oceanographic community to improve key scientific processes like ocean-atmosphere exchange, turbulent mixing etc., both of which have direct impact on our society. The Dynamo project develops innovative network-centric algorithms, policies and mechanisms to enable programmable, on-demand access to high-bandwidth, configurable network paths from scientific data repositories to national cyberinfrastructure facilities, and help satisfy data, computational and storage requirements of science workflows. This will enable researchers to test new algorithms and models in real time with live streaming data, which is currently not possible in many scientific domains. Through enhanced interactions between Pegasus, the network-centric platform, and new network-aware workflow scheduling algorithms, science workflows will benefit from workflow automation and data management over dynamically provisioned infrastructure. The system will transparently map application-level, network Quality of Service expectations to actions on programmable software defined infrastructure.

  • Parasol II

    NSF funded an experimental green datacenter called Parasol, which has previously demonstrated that the combination of green design and intelligent software management systems can lead to significant reductions in energy consumption, carbon emission, and cost. The enhanced version of this project will update energy sources, network technologies and management software. Running real experiments in live conditions using Parasol led to findings that were not possible in simulation. This research seeks to update and enhance Parasol with current and next generation power-efficient servers, improve network connectivity and integrate software-defined networking (SDN) and Wi-Fi capabilities, increase solar energy generation capacity, add a low emission fuel cell power source, diversify energy storage, and improve the cooling system to advance green computing.

  • EuroSea

    Although the Ocean is a fundamental part of the global system providing a wealth of resources, there are fundamental gaps in ocean observing and forecasting systems, limiting our capacity in Europe to sustainably manage the ocean and its resources. Ocean observing is “big science” and cannot be solved by individual nations; it is necessary to ensure high-level integration for coordinated observations of the ocean that can be sustained in the long term. EuroSea brings together key European actors of ocean observation and forecasting with key end users of ocean observations, responding to the Future of the Seas and Oceans Flagship Initiative. Our vision is a truly interdisciplinary ocean observing system that delivers the essential ocean information needed for the wellbeing, blue growth and sustainable management of the ocean. EuroSea will strengthen the European and Global Ocean Observing System (EOOS and GOOS) and support its partners. EuroSea will increase the technology readiness levels (TRL) of critical components of ocean observations systems and tools, and in particular the TRL of the integrated ocean observing system. EuroSea will improve: European and international coordination; design of the observing system adapted to European needs; in situ observing networks; data delivery; integration of remote and in-situ data; and forecasting capability. EuroSea will work towards integrating individual observing elements to an integrated observing system, and will connect end-users with the operators of the observing system and information providers. EuroSea will demonstrate the utility of the European Ocean Observing System through three demonstration activities focused on operational services, ocean health and climate, where a dialogue between actors in the ocean observing system will guide the development of the services, including market replication and innovation supporting the development of the blue economy.
