Professor Walba's research focuses on the design and synthesis of liquid crystals, with an emphasis on chirality and polarity in liquid crystal systems. Working in collaboration with the group of Professor Noel Clark in the Department of Physics, Walba's group has made key contributions to the development of ferroelectric liquid crystals and devices, which are now found in commercial consumer electronics products. Current research in the group includes: studies directed towards developing an understanding of the helical nanofilament phase, a novel organic nanoparticle system; Design, synthesis, and characterization of materials possessing the unique ferroelectric Smectic A Polar phase; Creating new materials designed to improve understanding of the heliconical nematic phase; the design, synthesis, and characterization of new liquid crystalline organic semiconductors, research on the Dark Conglomerate liquid crystal phases, and research on the Ferroelectric Nematic phase.
