Welcome Remarks (English / Japanese / Top)

Research Field: Welcome to the Optical and RF-MEMS Lab with Prof. Hiroshi Toshiyoshi and his colleagues. We are a research group within the Center for International Research on Mironano Mechatronics (CIRMM)*3 located at the Institute of Industrial Science (IIS)*4, The University of Tokyo, Tokyo, Japan. Our research interest is in the optical and RF-MEMS*5 application of MEMS technology. Recently, we started a project on MEMS THz*6 filters.


Research Topics: You may find our research topics (accomplishment and on-going) at Research. Our lab life can be sampled at Lab Daily Life page. Click on the links on the left to find more about us, such as Members and Publication.

Student Admission: Our lab accommodates graduate school students (master and Ph.D course) within the EE (Electrical Engineering) course of the University of Tokyo. Entrance exam information and lab topics for candidate students are at research high-light.

International Activities: We operate the Core-to-Core Program (A. Advanced) entrusted by the JSPS*7 from April 2012 to March 2017 as a matching fund to the EU-FP7*8 (EUJO-LIMMS)*9 granted to the France-Japan collaboration lab LIMMS*10; in this program, young researchers higher than the master-course level are dispatched to our oversea collaborating labs for their international research training. We also join the G-COE*11 program of the EE department of the University of Tokyo (completed as of March 31, 2012).

National Project: From February 2011, we participate a national program of the JSPS (Funding Program for Next Generation World-Leading Researchers) and conduct Integrated MEMS Technology for Multi-functional Low Power Electronics (four year program).
