Gaku Okuma | WRHI – Tokyo Tech World Research Hub Initiative

Biography

I graduated half year early, and obtained a PhD at Tokyo Institute of Technology in September. I continued the work
as a JSPS research fellow. I am now a specially appointed assistant professor at Laboratory for Materials and Structures since April 1st.

Expectations for WRHI

I would like to discover a new tough ceramics and elucidate a toughening mechanism from the view of microstructure by using advanced technique, such as X-ray CT.
