Professor Teruya Ishihara graduated from Department of Physics, the University of Tokyo in 1981 and continued to study in its graduate school. In 1984, he started working as an Assistant at Department of Physics, Tohoku University till 1993.  During the period he received PhD from Tohoku University and stayed at Brown University as a visiting researcher in 1990-1992. He was an Associate Professor at Department of Physical Electronics, Hiroshima University during 1993-2000. He was a head of Exciton Engineering Laboratory at Frontier Research System, RIKEN in 1999-2007. He came back to Tohoku University in 2003 as a full professor and retired in March, 2023. 

Professor Ishihara's research interest has been experimental investigation on optical properties of materials with characteristic features (especially related to optical nonlinearity), including layered semiconductors, semiconductors and metallic thin films with artificial sub-wavelength structures (metamaterials and metasurfaces).
