Tomohiro Nakatani received his B.E., M.E., and Ph.D. degrees from Kyoto University, Japan, in 1989, 1991, and 2002, respectively. He joined the Basic Research Laboratory of Nippon Telegraph and Telephone (NTT) Corporation, Japan, in 1991. Since then, he has been investigating sound capturing techniques directed at both humans and computers, including speech enhancement and automatic speech recognition. In particular, he developed a speech separation method based on harmonicity and location of sources in 1996, he presented a robust speech fundamental frequency estimation method in the presence of background noise in 2002, and he proposed a blind speech dereverberation method based on a probabilistic model of speech signals in 2007. He is now a senior research scientist of NTT Communication Science Laboratories, NTT Corporation. He has been a Visiting Associate Professor at Nagoya University since 2008. From 2005 to 2006, he visited Georgia Institute of Technology as a visiting scholar, and worked with Prof. Biing-Hwang (Fred) Juang. He is the author or coauthor of six book chapters, 22 journal articles, more than 60 international conference papers. He is a Technical Program Chair of the IEEE WASPAA-2007, a member of the IEEE CAS Blind Signal Processing Technical Committee since 2007, and a special session organizer of the IEEE ISCAS-2007 and the IEEE ICASSP-2009. He has been an Associate Editor of the IEEE Transactions on Audio, Speech, and Language Processing (TASL) since 2008, and the Secretary of the IEEE Kansai Section Technical Program Committee since 2009. He has been reviewing a lot of papers for the ICASSP Speech and Audio TCs, the IEEE Trans. ASLP, the Journal of Acoustical Society of America, Speech communication, and many other international conferences and journals. He received the 1997 JSAI Conference Best Paper Award, the 2002 ASJ Poster Award, and the 2005 IEICE Best Paper Award. He is a senior member of IEEE, and a member of ASJ, and IEICE.
