The pinyin given by op has a one to one mapping to the pronunciation, and it seems a bit inconsistent that they fully Romanized their names while leaving Ngô Bảo Châu in the Vietnamese alphabet. But even if they did (and I believe this was what op was getting at) afaik there wouldn&#x27;t be a one to one correspondence between surname pinyin and character. Incidentally, my sense is that their is broad awareness of these problems, at least in academic circles, which have a kind of &quot;your name is your brand&quot; attitude, and its common to see both short and full names in publications.
