Current Research Projects
Galileo
Galileo is a geospatial data storage system that is designed to provide efficient access to time varying geospatial datasets from observational instruments. The storage system is designed to enable large-scale visualizations and processing of geospatial datasets. I designed the algorithms that are responsible for the organization and dispersion of data and also the evaluation of queries.
ADDS
Atmospheric Data Discovery Network Service (ADDS) enables discovery of observational, binary datasets managed at multiple data hosting services. Datasets are packaged and published by organizations at regular time intervals. ADDS parses binary datasets to generate metadata, which is used to allow random accesses to specific portions of the published data. ADDS provides programmable query interfaces to automate discovery mechanisms, and supports the binary BUFR format that is the World Meteorological Organization’s standard for observational data, and also netCDF a format often used to encode outputs of simulation models.
Past Research Projects
SWARM: Meta scheduling framework that interoperates with Globus and Condor clusters to manage the execution of a large number of jobs.
myLEAD: Data cataloging system for scientific workflows used for tornado predictions.
CAROUSEL: Data processing framework for collaboration over handheld devices.
