For matters strictly related to NTT: mehdi.tibouchi@ntt.com (note that earlier addresses in @lab.ntt.co.jp and @hco.ntt.co.jp are deprecated and may no longer work).

For matters strictly related to Kyoto University: tibouchi.mehdi.5n@kyoto-u.ac.jp.

For everything else: mehdi.tibouchi@normalesup.org.

And for important matters, it can be a good idea to send a copy to the following address in case one of the previous ones has a temporary hiccup: mtibouchi@gmail.com.

I am not very active on social media, but I do have accounts on Twitter/X and LinkedIn. I occasionally answer questions on the Cryptography StackExchange. My pages on Google Scholar, DBLP and the IACR CryptoDB may also be relevant.
