GEMSFITS Development Team


 Authors

G. Dan Miron (IGP, ETH Zurich):  Main developer since October 2012, supported by the ETHIIRA PhD project on fit standard-state thermodynamic properties of aqueous species against experimental solubility data at hydrothermal conditions.

Dmitrii A. Kulik (Paul Scherrer Institut): architect of GEMSFITS code collection; maintains coupling between gemsfit2 and GEMS3K kernel equilibrium speciation solver; develops extensions to fit standard-state properties of solid solution end members and reciprocal energies against experimental data (SNF Sinergia C-A-S-H project).

Svitlana V. Dmytrieva (Ciklum Interactive Solutions, formerly Institute of Environmental Geochemistry, Kyiv, Ukraine): design and implementation of the gfshell2 GUI shell code, data import-export functionality, spreadsheet and graphical visualization.

Thomas Wagner (Division of Geology, University of Helsinki, Finland; formerly IGP, ETH Zurich): maintains coupling between gemsfit2 and TSolMod library of models of mixing in phases-solutions, supervises the ETHIIRA PhD project.

Georg Kosakowski (Paul Scherrer Institut): Supervises selection and interaction of statistical methods and parameter fitting algorithms.

The early prototype - the GEMSFIT code - has been developed since 2010 until mid-2012 by:

Ferdinand F. Hingerl (joint position at LES PSI and IGP ETHZ in association with the CCES GEOTHERM project; since August 2012 at ERE, Stanford University, USA).

Collaborators

Barbara Lothenbach (Empa, Duebendorf, Switzerland): optimization of thermodynamic properties of end members and interaction parameters for the novel solud solution models of calcium silicate hydrate (C-S-H) phases with aluminum and alkali, based on original solubility and co-precipitation data (E.L'Hopital, Empa) supported by SNF Sinergia C-A-S-H project; supervision of Nanocem internal project.
