Although we won't know for sure until future episodes air, it's worth remarking that the official StarTrek.com database claims that he died:
Starfleet Admiral at the Battle at the Binary Stars. He was killed when a Klingon cleeve ship attacked the U.S.S. Europa.
However, being dead doesn't mean he won't appear in future episodes; Discovery has already demonstrated that it isn't afraid of flashback scenes, for example.
