Over 40 years of managerial and technical experience in science data systems development, image processing, remote sensing, parallel processing, algorithm development, and science data processing. Received Office of Personnel Management’s Certificate of Executive Qualifications in October 1995 after successful completion of NASA’s Senior Executive Service Candidate Development Program (SESCDP).
Currently Research Scientist/SME, Science Systems and Applications, Inc., working as a contractor on NASA projects. The focus of this position is on data stewardship for and preservation of remotely sensed data and derived products from NASA missions. Most recently held positions prior to current position were Assistant Project Manager and Chief of the ESDIS Science Office of the Earth Science Data and Information System (ESDIS) Project at NASA’s Goddard Space Flight Center. This Project develops and operates one of the largest civilian science data systems in the world - the Earth Observing System (EOS) Data and Information System (EOSDIS) in support of NASA’s Science Mission Directorate (SMD). The ESDIS Project has been instrumental in establishing, as a part of EOSDIS, a set of Distributed Active Archive Centers (DAACs) around the US that manage NASA’s Earth science data and provide convenient access to petabytes of data in various scientific disciplines such as land processes, oceanography, hydrology, atmospheric sciences, cryospheric studies, etc. The Project has also developed systems that facilitate “one-stop shopping” access to international data centers. Dr. Ramapriyan’s responsibilities in the Project ranged from supervising a group of technical professionals in the design and implementation of EOSDIS, managing Science Investigator-led Processing Systems (SIPS) and managing the early establishment, development and operation of the DAACs to providing a customer focus by interfacing with the scientific customer community to understand their requirements and assuring that the system development accommodated their requirements. He was a member of the Strategy for Evolution of Earth Science Data Systems (SEEDS) Formulation Study Team and a member of the EOSDIS Evolution Technical Team. He was a member of the ESDIS Project’s Executive Council overseeing the NASA Earth Science Data System Working Groups (ESDSWG). He was the ESDIS Project’s lead for the ESDSWG’s Data Stewardship Interest Area.
In addition, Dr. Ramapriyan supported the Intelligent Systems Project (ISP) within the Computing, Information and Communications Technology (CICT) Program, managed by NASA’s Ames research Center. Within the ISP, Dr. Ramapriyan was the Deputy Manager for Intelligent Data Understanding (IDU), one of three technical areas. This was a basic research program in computer sciences with significant participation by the university community to advance the state of the art for solving problems relevant to NASA’s future missions. Dr. Ramapriyan led a study on Intelligent Archives in the Context of Knowledge Building Systems in support of ISP/IDU and was responsible for developing a testbed implementing some of the IDU PIs’ algorithms to demonstrate their scalability to a proto-operational environment.
During1998 - 2007, Dr. Ramapriyan also served as an Adjunct Faculty member at the Bowie State University and taught one or two courses per semester as requested by the University. He taught courses in Computer Science at the Senior and Graduate levels (Image Processing, Data Base Management and Data Mining). He has been an Affiliate Faculty member at the George Mason University’s Department of Earth Systems and Geo-Information Sciences and a member of the Graduate Faculty.
