Chikayoshi Sumi received the B.E, M.E., and D.E. degrees from the Department of Electrical and Electronics Engineering, Sophia University, Tokyo, Japan, in 1991, 1993, and 1996, respectively. From 1996 to 1998, he was a research fellow of the Japan Society for the Promotion of Science and a research associate at Sophia University. In 1997, he was with the Bioacoustics Research Laboratory at the University of Illinois at Urbana-Champaign as a visiting scholar. He started to work at Sophia University as a lecturer, and he currently is an associate professor at the Department of Information and Communication Sciences. His research interests include medical ultrasound, elasticity imaging, non- invasive treatment, biological signal processing, and inverse problems etc. He is a senior member of the IEEE, and members of the Japan Society of Ultrasonics in Medicine, the Japan Society of Medical Electronics and Biological Engineering, the Institute of Electronics, Information and Communications Engineers of Japan, and the Institute of Electrical Engineers of Japan. He currently is editorial boards of Journal of Reports in Medical Imaging, Journal of Medical Engineering, and International Journal of Biomedical Imaging.(Subject of research)
