Horst Henning Winter

Winter founded 2D Matter LLC in 2018. It promotes the engineering of two-dimensional materials such as clay, graphene, zeolite, as generated by the exfoliation of precursors with layered structure.

In 2007, Winter founded IRIS Development LLC, a software service company in support of experimental rheology and rheology education. The company holds the 'Amherst Rheology Courses' and licenses IRIS RheoHub, a software tool used for research and teaching by academic researchers, and by industrial decision makers so that they can utilize rheology efficiently. A main feature of the software is the visualization of rheology results by a direct overlay of experimental data and predictions from rheology theory.

In 1996, Winter was awarded the Bingham Medal in recognition of his contributions to experimental rheology, as well as rheometry of gels and polymer melts. He was also chosen for the National Science Foundation Creativity Award in 1997 and the Alexander von Humboldt Senior Scientist Award in 1999, during which he was a visiting professor at the Max Planck Institute of Colloids and Interfaces in Potsdam. Winter is furthermore the co-founder of IRIS Development and founder of 2D Matter. Winter lives with his wife Karin. They have four children.

Horst Henning Winter is a German American chemical engineer, educator and researcher. He is a distinguished professor at the University of Massachusetts Amherst, and was the executive editor of Rheologica Acta from 1989 to 2016, where he has served as honorary editor since 2017.

He was the executive editor of Rheologica Acta from 1989 to 2016, served on the editorial board of Journal of Rheology from 1989 to 2005, and of Journal of Non-Newton Fluid Mechanics from 1989 to 2018. From 2009 to 2012, he served as director of the Fluid Dynamics Program at the National Science Foundation (NSF), after which he returned to UMass.

Winter also contributed to the numerical modeling of polymer processing operations and his 1977 paper on viscous dissipation in flowing polymer systems is widely considered a classic in the area.

Winter began his teaching career as Privatdozent for Rheology at University of Stuttgart in 1976. He transferred as associate professor to the University of Massachusetts Amherst in 1979, becoming full professor in 1984, and was named distinguished professor in 1994. At the same time, he also became the director of the Laboratory for Experimental Rheology.

Winter was born in Stuttgart, Germany in 1941. He obtained a Dipl-Ing. in Mechanical Engineering at the University of Stuttgart in 1967. He then received an M.S. from Stanford University in Chemical Engineering in 1968. He returned to University of Stuttgart where he completed his Ph.D. in 1973 in Polymer Rheology, an interest he continued pursuing immediately after graduation through work as a DFG (German Research Foundation) fellow at the Rheology Research Center at the University of Wisconsin-Madison. In 1976, this led to a habilitation thesis on viscous dissipation in polymer flow.
