Of course there are. All members of MRL are professional academic cryptographers. There's Surae, Sarang, Shen, etc.
Meanwhile the background and "academic" activities of most of the academics behind Zcash are quite sketchy despite their fame. People will come to see this before long.
The bios of those three say they have degrees in mathematical sciences, physics, and algebraic geometry, respectively. None of those are cryptography. On top of that, they're pseudonymous, so we can't even verify these claims.
ZCash has well-known people, employed at places like Johns Hopkins and Berkeley, who specialize in cryptography and have long lists of publications to their names. If anyone is going to be called "sketchy" it should be the people hiding behind pseudonyms.
I don't own ZCash or Monero, so I don't have a dog in this fight except that I get annoyed at the Monero community's strident insistence of their intellectual superiority over ZCash.
They are not hiding behind pseudonyms and attend meetups regularly, stuff like RingCt was peer revieewed by legder journal...
And yes i call zcash skechy too, creating a currency with a trusted setup and stuffing 10% off all mining rewards in your pockets its an outright scam.

Whereas the ZCash team includes several people who were well-known cryptographers before ZCash came along.
