Mary Thomas, is a member of the faculty in the Department of Computer Science the Computational Science and Engineering Research Center at San Diego State University, and the Coastal Ocean Dynamics Research Group.
Thomas' research interests focus on computational science, parallel programming, and advanced computational environments that support high-end scientific applications.
Current projects include investigation into parallelization of nested, 3D staggered grid coastal ocean models, such as the General Curvilinear Coastal Ocean Model (GCCOM). GCCOM is a non-hydrostatic, large eddie simulation (LES) CFD model capable of running both ocean and atmospheric simulations at very high resolutions (meter-scale). Parallelization approaches include MPI and GPU techniques. For the nested model research, a new model is being developed which nests the GCCOM model within a coarser, global ocean model (kilometer scale). Initial studies will investigate the effects of larger-scale processes influence non-hydrostatic features such as shoaling internal waves and bores which impact diapycnal mixing, transport processes, and a host of biological/ecological processes such as larval connectivity and the transport of low dissolved oxygen/pH waters to the nearshore.
In addition, Thomas works on the development of computational environments (CE's) involve the use of emerging technologies and cyberinfrastructure to integrate advanced computational, data, and networking infrastructure. Research projects include development of the Cyberinfrastructure Web Application Framework (CyberWeb). CyberWeb is designed to facilitate development of virtual environments (VOs), Web services, and portals associated with scientific and high-performance computing. CyberWeb utilizes Cyberinfrastructure (CI) and emerging distributed, Web, and portal technologies.
