Yaxing Wei

Lead Scientist, ORNL DAAC

Yaxing Wei is the Lead Scientist for the ORNL Distributed Active Archive Center (DAAC) and a geoinformatics data scientist at the Remote Sensing and Environmental Informatics (RSEI) group in the Environmental Sciences Division. Since joining ORNL in 2008, Wei has been dedicated in data management, visualization, sharing, and analysis for a number of research projects, including the ORNL DAAC, the Multi-scale Synthesis and Terrestrial Model Intercomparison Project (MsTMIP), and the Data Observation Network for Earth (DataONE). He created the Spatial Data Access Tool (SDAT), a Web-based data infrastructure that standardizes a large collection of environmental sciences data archived at the ORNL DAAC and allows data users interactively visualize and download data in forms fitting their specific needs.

Wei’s research interests include leveraging cutting-edge geospatial information standards and technologies to increase the Findability, Accessibility, Interoperability, and Re-usability (F.A.I.R) of scientific data and enables researchers focus on science analysis instead of data preparation. He is also interested in developing data fusion and machine learning techniques to produce data products that support environmental, meteorological, and renewable energy researches and applications.

Wei is an IEEE Senior Member. He received the International Council for Science's World Data System (WDS) Data Stewardship Award in 2015. He is currently serving in the NASA Earth Science Data and Information System (ESDIS) Standards Office (ESO).
