Katsuhiro Ajito received the Ph.D. degree in applied chemistry from the University of Tokyo, Tokyo, Japan, in 1995. He is a Senior Research Scientist and Leader of the Terahertz Spectroscopic Analysis Project at the Smart Devices Laboratory, NTT Microsystem Integration Laboratories, Atsugi, Japan. He joined NTT Basic Research Laboratories in 1995. From 1995 to 2007, he studied glutamate in single synapses using Raman spectroscopy and laser tweezers. His current research interests include nano- and biochemistry studied by terahertz spectroscopy and imaging techniques. Dr. Ajito received the Young Scientist Award for the Presentation of an Excellent Paper from the Japan Society of Applied Physics (JSAP) in 1999. He has been the Chair of the Terahertz Spectroscopy Division of the Spectroscopical Society of Japan (SSJ) since 2005. He is a member of IEEE, SSJ, JSAP, the Chemical Society of Japan (CSJ), and the American Chemical Society (ACS).
