April 2012 – Present: University of Texas at Austin
Research Fellow, Jackson School of Geosciences (4/12 – Present)
Research Scientist, Cockrell School of Engineering (10/12 – Present)
UT Center for Integrated Earth System Science (CIESS) director Dr. Liang Yang and associate director Dr. David Maidment invited me to be Research Fellow in this new research center, formed in 2011. Goals are to support and help organize interdisciplinary research in geosciences, engineering, and public policy across UT schools and departments; conduct seminars and webinars for outreach; and support UT’s access and influence in international standards communities. Due to my level of activities by 2014, I was appointed as Research Scientist in June 2014.
Am continuing my participation in NSF EarthCube, started while OGC staff:
Am coordinating two NASA grants to develop applications for public use of NASA's Land Data Assimilation System (LDAS) model outputs of soil moisture, evapotranspiration, runoff, and other variables at national and global scales.
2013: started coordinated endowments for the Jackson School of Geosciences and the Information School, to advance research and applications in digital preservation of physical geological and other collections in Earth sciences.
2013: Completed my role as co-chair of the Standards and Interoperability Forum (SIF) of GEOSS, started while OGC staff. The SIF helps develop and educate on use of the GEOSS infrastructure.
Adjunct Faculty, School of Information (1/13 – 12/13)
Taught graduate-level GIS Introduction course for two semesters in 2013. Could not continue after Fall 2013 due to other work commitments. Course syllabi available for limited time at Spring2013: INF 385T and Fall 2013: INF 385T.
Research Fellow, School of Information (3/14 – Present)
Continuing my relationship with iSchool by connecting other faculty with EarthCube and OGC projects, and with endowment activities.
July 2012 - Present: Research/Academic Advocate, Open Geospatial Consortium, Austin TX
This is an outreach role that runs in parallel with my positions at UT Austin. The goals are to stimulate greater use of OGC and related standards for "locatable-data exchange" within the broader research community, and to strengthen the contributions from these communities to influence and advance the evolution of OGC's process and standards. See also staff bio page at OGC website, and my blogs on OGC .
June 2008 - June 2012: Director, Interoperability Programs, Open Geospatial Consortium, Austin TX
My primary responsibility was to organize and lead sponsored test beds (OWS-6, OWS-7, OWS-8) to advance standards, best practices, and cyberinfrastructures for sensor web, geoprocessing workflow, security & event architectures, visualization, and decision support, each resulting in a set of reports & demonstrations (OWS-6, OWS-7, OWS-8). I also initiated and led development of these videos: About OGC and OWS-8 Demonstrations Overview.
August 2006 - May 2008: President and Chief Technology Officer, OGC Interoperability Institute, Austin TX
Directed the OGCii program for education and outreach to advance the interoperability of digital scientific data collections in the geosciences and for institutional spatial data infrastructures (SDI). Helped plan and conduct technical workshops and pilot studies to develop and test systems for interoperability across multiple application domains. Helped identify and recruit government, academic, and commercial partners for specific projects, helped write grant proposals, and the technical and executive reports of these projects. Key project during this period was for requirements analysis and architecture of the Pennsylvania Map SDI (PAMAP). Also helped convene sessions on interoperability and open science at AAAS conferences.
