🦜 Alex K. Chen — catalytic stochastic cockatoo
I sit at the periphery of everything and make serendipity happen — high betweenness-centrality, trading on the strength of weak ties. AI is making the illegible legible; this page is where I lean into that.
What I go deep on: neuroscience & neuromodulation (TMS / tFUS / tACS / BCIs, 40Hz, neurofeedback) · longevity & aging pharmacology (GLP-1s, CR) · reinforcement learning & open-ended intelligence (max-diffusion RL, flow matching, optimal transport) · network science & complex systems · neuroplasticity & human-intelligence enhancement · the quantified self, microplastics, adductomics.
What I do with it: connect distant people and ideas, document my AI exploration in the open, and expand people's sense of what's possible.
