Sienna Geodynamics (SGC) is an S-Corporation registered in New York State, with Dr. Park as the owner/operator. This company has been providing consulting services since 2003 for applying water-rock interaction and reactive-transport simulators to geochemical problems, and also developing task- or application specific simulators for academic partners and private industry clients.

The primary simulator, Sym.8, was designed and developed by Dr. Park, and its technical core is published in the article published in 2014. Dr. Park received his B.S in Geology from University of Washington, Seattle, WA., and M.S and Ph.D from Indiana University, Bloomington, IN in Geology and Theoretical Aqueous Geochemistry. Dr. Park has been developing water-rock interaction and basin simulators since 1980's through his M.S., Ph.D., and post-doctoral research at Indiana University, and as a post-doc at the French Institute of Petroleum in France. Development of task-specific and customized simulators, and their applications, are ongoing.

Dr. Park was also the primary architect and manager of a basin-scale simulator that incorporated multiphase flow, compactional overpressure development, fracturing, and elasto-visco-plastic (rheological) deformation (Tuncay et al, 2000a, 200b), a program which was built by a multi-disciplinary team over a five-year period (1997-2003, Indiana Univerisy). Other mentionable publically funded and published projects of significant interest and achievements include contribution to linked kinetic organic maturation model (Payne et al, 2000), and authoring and completing an iron-oxide concretion nucleation simulator using a diffusion-reaction approach (Park et al., 2006; Chan et al, 2007).

Direct and indirect previous involvment of the PI on 1- to 3-dimensional geologic problems that are relevant to diagenesis, carbon sequestration, and other reactive-transport processes include projects on reaction-front instability, acidizing, and worm-holing in reservoir systems (Park and Ortoleva, 2003; Chen et al., 1990; Ortoleva et al., 1996; Liu et al., 1997; Ormond and Ortoleva, 2000), composition-driven diagenesis in clastic sediments (Thyne et al., 2002a; 2002b), early carbonate diagenesis (Budd et al., 2002, 2007; AVID carbonate diagenesis consortium, University of Colorado at Boulder, CO), and reservoir quality characterization (Balance Clastic Diagenesis Consortium, this company).

Computer simulators and consulting services that are currently being developed by SGC not only take advantage of Dr. Park�s familiarity with the industry, but also of the shortcomings of alternative technologies currently available. Simulation programs of SGC integrate fundamental basic sciences with recent advances in computational sciences, applied mathematics, and Internet-based technologies. Advances in computers and mathematics allow highly sophisticated simulators to be developed for use in industrial environments, while the Internet-based technology allows cost-effective delivery of simulators with user-friendly graphical and database interfaces.

The goal of this company is to develop and deploy industrially viable geotechnical simulators, and to provide continuing and necessary support services to all pertinent geological and geo-engineering clients.
