Prof. Yokoyama is a world expert in the field of liquid crystal physics with a focus on the surface properties. His primary research interests are in the areas of liquid crystals, surface and colloid science, organic thin films and scanning probe technology.Yokoyama received his Doctor of Engineering (1987) from the Tokyo Institute of Technology. Before joining the Liquid Crystal Institute, he was the director of Nanotechnology Research Institute (NRI), National Institute of Advanced Industrial Science and Technology(AIST). He joined the LCI staff in July 2009 as an Ohio Research Scholar and professor in the Chemical Physics graduate program. His research effort at the LCI will be associated with the recently funded by the State of Ohio’s Third Frontier Project entitled Research Cluster on Surfaces in Advanced Materials (RC-SAM). RC-SAM is the partnership of Kent State University, Case Western Reserve University, Youngstown State University, Alpha Micron, Inc., Cleveland Botanical Garden, CoAdna Photonics, Inc., Kent Displays, Inc., Kent Optronics, Inc., and LXD, Inc.
