Since September 2019, Chaitan Baru has been on assignment at the National Science Foundation as Senior Science Advisor in the Office of Integrative Activities, Office of the Director, NSF. His responsibilities include providing technical leadership for the Open Knowledge Network (OKN) track of the NSF Accelerator. He has previously been on assignment at NSF, from August 2014- August 2018, as the first (and only) Senior Advisor for Data Science in the Computer and Information Science and Engineering Directorate (CISE), NSF. During that time, he co-chaired the NSF Harnessing the Data Revolution Big Idea; played a leadership role in the NSF BIGDATA program; and advised the NSF Big Data Regional Innovations Hubs and TRIPODS programs. He was instrumental in establishing the partnership between the NSF BIGDATA program and the public cloud providers--AWS, Google, Microsoft, and IBM in 2017 (IBM joined in 2018).

He is on assignment at NSF from UCSD, where he is Senior Advisor, Data Science Research Initiatives for the Office of Research AffairsSan Diego Supercomputer Center, and the Halicioglu Data Science Institute.

Baru has served in a number of roles at SDSC, including Co-Program Director, Data and Knowledge Systems; Division Director, Science R&D; and Associate Director of Data Initiatives. He established and directs the Advanced Cyberinfrastructure Development lab and the Center for Large-scale Data Systems Research (CLDS). He has a broad set of research interests in the area of translational data science that includes topics in applied and application-oriented research in data management and data analytics.

He has led/co-led a number of data cyberinfrastructure initiatives, including as Principal Investigator (PI) of the OpenTopography project; Cyberinfrastructure Lead, Tropical Ecology, Assessment and Monitoring Network (TEAM); Co-Investigator of the Cyberinfrastructure for Comparative Effectiveness Research project (CYCORE); Member of the founding Senior Management Team of the National Ecological Observatory Network (NEON) and Co-PI of the NEON Cyberinfrastructure Testbed; Co-PI of the CUAHSI Hydrologic Information Systems (CUAHSI-HIS); Director, NEES Cyberinfrastructure Center (NEESit); PI/Project Director, Geosciences Network (GEON); and member of the How Much Information? project.

Prior to joining SDSC in 1996, Baru was at IBM, where he led one of the development teams for DB2 Parallel Edition Version 1 (released Dec 1995); and at the University of Michigan, where he served on the faculty of the EECS Department. He received his B.Tech in Electronics Engineering from the Indian Institute of Technology, Madras, and M.E. and Ph.D. in Electrical Engineering from the University of Florida, Gainesville.
