Gerald G. Fuller

Fuller is a research specialist in the science of rheology. In this field, he has developed numerous optical and mechanical experimental techniques to probe the structure and dynamics of complex fluids including colloids, emulsions, collagen fiber suspensions, and human meibum. His laboratory crafted techniques to make accessible automated optical probes of fluid structure that take advantage of the many interactions of light with flowing matter; for example, polarimetry (birefringence and dichroism). He also designed an interfacial stress rheometer that has achieved the highest sensitivity in the measurement of interfacial material functions, which fostered development of new classes of instruments capable of fast, sensitive responses to flow-induced changes in microstructure that are responsible for non-Newtonian behavior.
