Real Alpha has cut 8 moments of Alex Reeves talking, from an interview on The Cognitive Revolution published Oct 20, 2026.
What Alex Reeves said
Cell models need information-rich data and useful inductive bias
“So what I think is possible now is an information theoretic model of the cell.”
Alex Reeves16:38 A laser phase plate reveals molecules inside living cells
“what this really gets you is the ability to look. And so the big application is cryo-electron tomography, which is basically sectioning the cell”
Alex Reeves26:52 Health records alone may reveal correlations, not causes
“because if you don't have the right basis, basically what you're going to learn is a bunch of correlations.”
Alex Reeves50:07 Biohub's initiative targets hundreds of billions of cells
“be able to do that at the scale of hundreds of billions or more cells.”
Alex Reeves25:06 Biohub is building imaging tools across biological scales
“track a developing zebrafish embryo over time and actually see and track every single cell”
Alex Reeves34:48 Protein models benefit from training across evolution
“And so there's, I think, something really powerful in this idea of generalization and transfer.”
Alex Reeves41:02 A coordinated effort could map cellular health and disease in five years
“within five years with a really focused coordinated effort, we can have, you know, a pretty comprehensive map there.”
Alex Reeves47:51 Biology models need lab-based verification loops
“ask the question perform the experiment learn from the experiment improve its understanding propose a better experiment”
