Bob Lemieux
Biography
Professor Lemieux's lab bridges the fields of organic synthesis, physical organic chemistry and condensed matter physics to create new liquid crystal materials that are used in fast switching ferroelectric and electroclinic LCD applications by taking advantage of their inherent structure-property relationships.
His research has resulted in a better understanding of how chirality (a molecule’s "handedness") propagates in smectic liquid crystal phases, which is leveraged to produce ferroelectric LCDs with faster response times, and in the development of new liquid crystal materials for the formulation of defect-free ferroelectric and electroclinic LCD applications.
His group is one of only a few chemistry groups in the world with the expertise necessary to synthesize new liquid crystal materials, characterize their physical properties, and evaluate their potential as active components of electro-optical and photonic devices.
