may adopt a value between -1 and 0. This behavior makes it easy to uniquely identify the gel point during both chemical and physical gelation processes. The experimental findings initiated active development of theories for the rheology of gels in the physics community. The findings also had technological impact, supporting the commercial development of gels as adhesives, sealants, toners, and biological materials. The original paper continues to be the most cited publication ever in the

With Alessio Zaccone, they also developed rheological scaling laws for colloidal gels, which take into account the power-law growth kinetics in the colloidal self-assembly.

For generating biaxial extension in small samples, Winter invented the technique of lubricated squeeze flow and studied it jointly with

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

In a series of papers, Winter and his co-worker
Fancois Chambon characterized the time-evolving rheology of polymers during gelation. They discovered that the gel point is marked by power-law relaxation over a wide range of frequencies/time-scales. Depending on the type of gel, the scaling exponent
