Carol Song's Profile Photo

Senior Research Scientist

Carol Song leads the Scientific Solutions group in developing advanced computing and data cyberinfrastructure to support scientific discovery and learning. She has more than 20 years of experience in high-performance and distributed computing, and software engineering to connect domain scientists to advanced cyberinfrastructure technologies. Since 2005, she has been PI or CoPI on more than 30 sponsored research projects, representing more than $32 million in research funding, including the NSF-funded TeraGrid and XSEDE, Data Interoperability, CI-TEAM, SDCI, SI2 projects, and most recently, a $5.2M NSF data infrastructure (DIBBs) project and a $4.5M NSF CSSI grant to develop reusable software and a data framework making large geospatial scientific datasets readily usable by domain scientists. She is the lead of the Purdue DiaGrid project (diagrid.org) that makes HPC resources accessible online applications delivered in web browsers, and of the MyGeoHub.org geospatial science gateway that supports data-driven collaborative research and learning.

Carol has broad engagement with the science and cyberinfrastructure communities nationwide and internationally. Song served as the inaugural chair of the XD Service Provider Forum (SPF) from 2011 to 2013, and on the XSEDE Advisory Board 2012-2015. She co-chairs the CODATA (International Council for Science: Committee on Data for Science and Technology) “Linked Open Data for Global Disaster Risk Research” Task Group, focusing on data issues in disaster risk research. Carol also served on program committees and as track chairs in conferences such as the TeraGrid and XSEDE annual conferences (2007-2015), Grid Computing Environments workshops (2009-2011), International Conference on Parallel Processing (ICPP); co-chair of special session on High Performance Geo-Computation at Geoinformatics 2009; Program Committee Chair of the 2011 Symposium on Data-Driven Approaches to Drought; chair of workshops and external programs for PEARC 2018. Carol has funded and mentored more than 60 students, including graduate, undergraduate, and high school students, in research projects. She has also served as a mentor to students at XSEDE, PEARC and Supercomputing conferences.
