Yuri Eden in Stephen Baxter's proxima what is his real name?

I have just read Stephen Baxter's PROXIMA and as it is early on mentioned in the novel, the protagonit's name "Yuri Eden" is not his real name. Yuri is the nickname he was given on Mars, Eden is the name of the Mars colony he lived in. Yet, I somehow missed his real name.

Over the course of the novel I began to suspect that he might be the original Robert Braemann. But this is only a speculation.

Is his real name mentioned in the novel or Have I missed something?
