The IRIS Mission:
IRIS stands for Interactive Rheology Information System. Our mission is to identify and overcome barriers to understanding and applying rheology. To do so, we use scalable rheology solutions that empower the science and engineering community to solve real-world problems. Our software platform, which supports this mission, has a central hub (IRIS Rheo-Hub) where rheological experiments and advanced theories can be easily juxtaposed so they can be efficiently analyzed, compared, categorized, viewed, “smart-plotted” and parameterized. A Smart Plot (SP) includes all its provenance; a single mouse click returns you to SP’s source data for further analysis and rheological modeling. - Our hub evolved over many years, and with the help of many contributors, and is known for its easy-to-use interface. In this way, the IRIS environment stimulates discovery and prepares for decision making.

IRIS Development LLC is a rheology consulting company. It was founded in 1996 and registered officially in January of 2007 as successor of a partnership 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's leading rheologists share their modeling codes.
"IRIS" is the abbreviation for Interactive Rheology Information Systems.

Mours 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.

Winter'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
analysis 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.
