Congrats, Yuya! The glue of a great MN-Osaka-ETH collaboration. Yuya was kind enough to collaborate w/ our group during both his masters at Osaka and PhD at ETH, ultimately coauthoring 5 papers (so far?) on 15N ssNMR and early TM imido catalysis. A real force of chemistry and great teammate!

Congratulations to Yuya, our synthesis-sensei and NCS analysis champion for the successful defence of his PhD thesis. He studied spectroscopic descriptors for reactivity of olefin conversion catalysts.
