We know Strohmeier was part of the group escaping from Theta because of his discussion with Brandon Wan (when Brandon sacrifices himself). Furthermore, in the Theta exit sequence after Simon wrenches his way out of the WAU dream state, there are four mind coral humans corresponding to each of the people I said didn't make it out of Theta (their entity names confirm their identities). If you approach these bodies, you can listen in on their sleep talking:
- Koster is in the train car to the right after you wake up out of the structure gel. She's dreaming of being on a date with Brandon.
- Strohmeier is at the far end of the first room you encounter the proxy in. He's dreaming of working on a plane or something with an old close friend named Doug.
- Goya is just before the vent in the hall where the proxy is patrolling, across from the alcove. He's dreaming that he's back at Delta and he finally beat Akers in a game of chess.
- Frost is to your right after crawling out of the vent. He's dreaming that he is announcing a major scientific discovery/breakthrough of some kind. (Possibly discovering alien life?)
If you're referring to the datamine in the dive room at Tau, the people involved are Steve Glasser, Sarah Lindwall, and Ian Pedersen (which is confirmed by looking at the lang entries of this conversation). Glasser is the guy at Tau who welcomes the ARK team upon their arrival and is the guy who accompanies Ross to the climber (and dies on the way). Pedersen is the guy who tells him about how everyone at Omicron thinks Tau is dead and who ultimately ends up killing Catherine. (I think we all know who Sarah Lindwall is.)
