  • Brief Bio

    Dr. Thomas Clune is a senior computational scientist at NASA GSFC and leads the Software infrastructure team within the Global Modeling and Assimilation Office.  Dr. Clune has ongoing software collaborations for the development of numerous models across several disciplines.  These include GISS ModelE2, NU-WRF, GEOS-5, DYNAMO, and MoSST. 

    Dr. Clune is a strong advocate for software testing within the scientific community and the originator and lead developer of pFUnit, an open source unit testing framework for parallel Fortran Software. The recently released version 3.0 of \ac{pFUnit} was completely redesigned to exploit the object-oriented features introduces in the Fortran 2003 standard. This highly-extensible framework has successfully been used in testing and development of several software packages within NASA, and is also being used at several prestigious institutions including \ac{ECMWF} and \ac{NCAR}.

    Dr. Clune currently serves as the Principal Investigator for the NASA Open-access Geo-ridding Infrastructure (NOGGIn) , that enables researchers to regrid data from disparate sources for further analysis.
