IRIS Development LLC is a rheology consulting company. It was founded in January of 2007 as successor of a parnership between H. Henning Winter and Marian Mours. H. Henning Winter is the sole member of the LLC (status Jan 2007). IRIS Development LLC holds all copyrights on "Rheo-Hub", the IRIS platform program for creative rheology work. Rheo-Hub supports rheological data exploration, data analysis, rheological modeling, data sharing, and repository. It is a platform at which the world'd leading rheologists share their modeling codes.
"IRIS" is the abbreviation for Interactive Rheology Information Systems.

Architects of Rheo-HubMours is currently working for a major German chemical company. He received his Ph.D. with H. Henning Winter at UMass Amherst in 1997. He also holds a diploma in chemical engineering from the University of Karlsruhe, Germany. In his Ph.D. work, he studied the rheological behavior of nearly critical gels. During his time in Amherst, he was involved in developing the Time Resolved Mechanical Spectroscopy (TRMS) approach for studying materials with changing properties. After having returned to Germany, Mours converted the IRIS code from DOS to visual C++ and added many new features and capabilities.
Dr. Marian Mours
Professor H. Henning WinterWinter's long-standing interest in experimental rheology began about 30 years ago when he could not find suitable rheological material data for his numerical calculations. Soon it became obvious that obtaining rheological data was not the main problem; converting these data into useful rheological material functions such as time spectra, viscosity, and modulus was the most difficult step. Little help was available here. A breakthrough came with Baumgaertel’s 1987 discovery of a robust method of converting dynamic mechanical data from the frequency to the time domain. This suddenly allowed an efficient data analysis and gave increased insight into the underlying phenomena. Since then, after much collaborative work, the data anlysis methods have become user-friendly and comprehensive while giving answers within minutes. The new methods have found widespread application. The original code was developed in collaboration with M. Baumgaertel and P. Soskey. M. Mours converted the original DOS code to visual C++ and introduced many methods from the literature. Recently, in collaboration with international experts, we extended the IRIS code and began to access molecular theory, non-linear viscoelasticity theory, and molecular simulation.
