s that proved transitions among such complex equilibria are continuous phase transitions ( chemical equilibria). More recently he has demonstrated thermally initiated microemulsion polymerization in bicontinuous microemulsions, wherein the expansion of the correlation length was only 20% relative to the precursor microemulsion, surpassing competitive attempts by two orders of magnitude. In more recent years, he has become a leading innovator in the fields of stimuli-responsive polymers ( smart polymers) and polymerized ionic liquids. Microemulsion polymerization of ionic liquid surfactant acrylates was used to produce transparent gels that reversibly undergo spinodal decomposition to open cell membranes and monoliths. Related nanolatexes have been formulated that appear to be the first experimental realizations of osmotic spheres. In August 2021, he resigned his tenure and was named Professor Emeritus by the EMU Board of Regents on 9 December 2021. He is currently pursuing collaborations with colleagues in Germany, Sweden, China, and the US. He is actively pursuing development of a new career and is seeking to develop and implement theoretical and experimental variational
