This listing provides a brief timeline & synopsis of "high points" from my activities since undergraduate days.
For explanation of acronyms, see Acronyms & Links page. Employment details and list of publications are on separate pages.
As I was working on my PhD, I could see that my previous
work experiences had given me many distinct perspectives on our societal
infrastructures in relation to the environment. DBMS and GIS are useful tools
for building and studying these infrastructures; they also highlight the
importance of data & model
interoperability for us to better understand and communicate about societal
and Earth systems across institutional boundaries. This has driven my professional interests ever since.

- Electric utility supply
and demand simulation modeling at UT Austin for my MSEE 1977-79, followed by
related work at SRI (programming support for SRI National Energy Model) and
EPRI (R&D planning studies and support), 1979-84;
- Relational DBMS and
object-oriented software programming and training development for various companies
in Silicon Valley

ecosystems modeling, and urban planning studies for my PhD at the University of
Florida in Gainesville, 1992-96;
- Studied ecosystem dynamics modeling from H.T. Odum, developer of a unique approach for holistic environmental accounting of any natural or human activity;
- Prototyped Smalltalk-based applications for Duke Energy, Florida Power & Light (field assets inventory and mapping)
- Trained & led Smalltalk development team based at NRL, Stennis Space Center, Mississippi, and managed source code version repository from UF in Gainesville;
- Developed Smalltalk-based visual editor for DIGEST VPF geospatial datasets: DNC, WVS, VMAP+;
- Building up software
development staff and data production capability as senior scientist for the
GIS software company Laser-Scan Inc, Sterling VA, 1996-99;
- Helped establish
relationship between Laser-Scan and US DOD, leading to Cooperative R&D
Agreement in 1997;
- Learning and describing
data models for several different application domains with GIS software company
Esri 2000-2006, published in a popular book, Designing Geodatabases: Case Studies in GIS Data Modeling (Esri Press, 2004);
- Leading the startup OGC
Interoperability Institute (an OGC affiliate member) to raise awareness of OGC
geospatial data exchange standards to the geosciences research community,
- Serving on OGC staff as
Director, Interoperability Programs, to lead OGC Web Services test beds, and to
support GEOSS and geosciences working group activities and outreach, 2008-12;
and in addition:
- Initiated and shepherded the relationship between
OGC and WMO resulting in OGC’s affiliate status with WMO since 2009 for
meteorology, hydrology, and climate standards development.
- Co-chaired GEOSS SIF 2008-2013.

system-of-systems development and interoperability, at Eye on Earth Abu Dhabi
Summit 2011, in preparation for Rio+20 in 2012.
- Invited to Advisory Boards of EarthServer and
ENVIROFI (FP7 projects in Europe).
- Co-PI for NSF EarthCube Governance Community Group,
helping develop initial roadmap for building governance structures within
- Shift from OGC to University of Texas at Austin, 2012-present:
- Teaching GIS and providing outreach about geospatial data exchange standards and practices at UT.
- Continued strong participation in NSF EarthCube governance and several other activities.
- Coordination of NASA ROSES ACCESS grants 2013-2016 to develop applications for public use of NASA Land Data Assimilation System (LDAS) products at national and global scales.
- Leading development of annual international projects to develop GEOSS Water Services conventions, practices and outreach.
- Starting endowments for digital preservation and modernization of geological collections at UT (2013).
- Maintaining connection with OGC as Research/Academic Advocate:
- Outreach to increase awareness, participation and influence of scientific research communities on the standards and technologies that could advance their research.
