About PI
Kuniharu Takei obtained his B.S. M.S. and Ph.D. in electrical engineering from Toyohashi University of Technology in Japan in 2003, 2006 
and 2009 under the supervision of Professor Makoto Ishida, respectively. As part of his Ph.D., he proposed and demonstrated a new type of MEMS/CMOS/Crystal-growth neural devices, which enable us to do in-vivo neural signal recording, local drug delivery, and local optical stimulation as well as on-chip signal processing. he has also shown the first proof-of-concept of neural signal recording and drug delivery using rats. In recognition of proposals and demonstrations, I became a research fellow of the Japan Society for the Promotion of Science (DC2) during Ph.D. students. Right after obtaining his Ph.D. degree, he moved to the University of California, Berkeley (Electrical Engineering Department) as a postdoctoral fellow under the supervision of Professor Ali Javey with a joint-appointment in the Material Science Division of Lawrence Berkeley National Laboratory. In the Prof. Javey group, he began by working on nanowire synthesis and its application of macroscale flexible electronics with low-voltage operation, resulting in becoming an artificial electronic skin (e-skin). This shows one of the promising approaches of nanomaterial integration on macroscle flexible substrates to the community of nanomaterial and devices. He also worked on freestanding ultrathin III-V semiconductor transistors by using an epitaxial layer transfer technique for high performance devices to replace current Si-based integrated circuits. 
    He joined Osaka Prefecture University (Department of Physics and Electronics) as a tenure-track assistant professor in 2013 April in Japan, where he is now an associate professor since 2017. He has been assigned as an editorial board member of Scientific Reports since 2014.
   He serves as a reviewer for Nature Materials, Nature Nanotechnology, Nature Communications, Nature Reviews Materials, Science Advances, NPG Asia Materials, Nano Letters, ACS Nano, Advanced Materials, Advanced Energy Materials, Advanced Functional Materials, small, etc. and a grant/proposal reviewer for the research foundations/programs in the US and Italy as professional contributions to the fields.
