A good next step would be to find out as much about Alexander and his work as possible.
+1, and his co-workers as per Esme's suggestion
It's a fairly sure bet that we are a result of his work one way or another.
Definitely, considering the circumstances of our awakening, and the Kell-Faber line
+1 to the plan, also yes, I agree we are likely Alexander’s work in some way

You make it clear your desire is to find out as much about Alexander and his work as possible.
"It won't be easy. As far as official policy goes, any of his work was destroyed and any mention of him in older works was purged. He used to be a rising star in the party so they had to get rid of all their praise to properly condemn him. Anything left about him is going to be in the hands of private owners, overlooked by censorship. Or in the minds of any of his old colleges. Approaching them will be dangerous though; its impossible to tell which ones are secretly sympathetic, which are cowards who will denounce him -and us- to survive, and which ones bought into the propaganda.
As I see it, we've got a few options to start with: First we can try to track down the pictured colleges in the book. They're the most solid leads. Second, we can kidnap some scientist currently working on that project you found out about. I'm sure we can get information out of him...or if you can just 'eat' him. That's up to your particular morality. Third, we can try to find where they're archiving texts of his. They have to exist; his work is too important for them to wipe it out purely to spite him and carry on with their propaganda message. They'll disavow it publicly and continue to use it in private, as we have already seen.
Those are my ideas, we can use any of them you'd like or if you have a reasonable plan I'd be good with that too."
