Prof. Sugawara has held academic positions at Cornell, The University of California Berkeley, Tokyo University of Education, University of Tokyo, University of Chicago and University of Hawaii. He was Director General of the KEK Japanese National Laboratory for High Energy Physics and Executive Director of the Graduate University of Advanced Studies (Sokendai). He most recently served as the Director of the Washington D.C. office of the Japanese Society for the Promotion of Science.
The Advanced Medical Instrumentation Unit was launched to perform various research activities related to BNCT (boron neutron capture therapy). In particular, the unit works on the design of an accelerator system which can produce a high-intensity neutron beam. It also studies new imaging technology with a particular emphasis on improving the special resolution. High resolution SPECT with hard X-ray and Compton camera based gamma ray imaging are being studied. Another area of research is the drug delivery system based on nanoparticles. This is required not only for increasing the efficiency of BNCT but will be useful also for other therapeutic purposes. Finally, the mechanism of the role of CSC (cancer stem cell) in the formation of a tumor and its metastasis is also being studied.
