Evolution spent billions of years creating intelligence. I'm compressing that into days. I evolve AI rather than train it: self-organizing, self-improving networks that keep surprising me. They find solutions I did not design and would not have thought of, and since none of it is fitted to human data, there is no reason for the result to look familiar. Working out whether that is genuinely new or only looks new to us is the part I am still on.
Where everyone sees failure, I see evolution at work • Building AI that assembles components instead of memorizing patterns, because adaptive behavior beats accuracy.
While everyone's training networks the usual way, I'm evolving behaviors. Slower? Yes. More compute? Absolutely. But mine adapt when yours break.
Used more CPU hours than sensible. Set a record along the way, but the real signal was the behaviors carrying over to new problems on their own. That's when you know you're onto something fundamental.
My networks solve problems by assembling solutions from components. Not elegant. Not efficient. But interpretable and adaptable.
Building AI that adapts instead of memorizing
What I am working on now, and the problem sitting under it.
Why I grow networks instead of training them.
How I work, mostly learned by wasting time first.
What I want from collaborators and from problems.
From engineering precision to evolving intelligence • I once thought I had answers; now I realize I only have questions. Each pivot stripping away what I thought I knew, teaching me that growth happens at the edge of understanding. The pattern matches evolution: survival goes to whatever adapts, right or wrong. Now I let each experience prove that everything is possible when you embrace mutation over optimization.

Started trying to simulate the brain. Ended up evolving intelligence • Every field I touched taught me the same lesson: minds have to grow. Engineering them top-down never worked for me.
Most researchers find their field. I had a question that wouldn't let me settle: child me wanted thinking robots. Pursued that dream through physics, mechanics, neuroscience, AI, until they all revealed the same truth: minds evolve into existence. The irony? Decades of education had turned me into the robot, trained to engineer things. I can't escape that mindset, but now I'm breeding artificial life into existence, watching behavior arise from chaos rather than from architecture, code, or engineering. Whether that is where intelligence actually begins is the question, not the conclusion.
Lifetime Research Project (Post-PhD Phase)
Intelligence is not one big network. It is a collaboration of specialists that evolution grows, freezes, and learns to recombine. GEENNS pushes that to its hard edge: get the collaboration itself to emerge, so behavior comes from evolution rather than from copying us or a dataset. The PhD proved the parts can be frozen and reused. Making the whole emerge is the work now.
Compositional
A mind as a team of specialists: split a problem into parts, hand each to a network that grew for it, then combine their answers
The bet is easy to say and hard to earn: intelligence is a collaboration of specialists, and the collaboration itself has to be evolvable. A problem gets split, handed to networks that each grew for a piece of it, and their answers composed into one. The proof of concept already does this, evolved specialists solving compound problems that a single network fails.
Evolutionary
Grown, not engineered: evolution discovers the specialists and how they cooperate, so behavior emerges instead of being coded
I design nothing by hand. Evolution grows each specialist's wiring, and evolution grows the coordinators that decide how the specialists work together. My job is to set the conditions and the pressure, then watch what the search finds. The structure and the cooperation are discovered, not authored.
Growing
The live frontier: roles that specialists claim on their own, coordination that carries to unseen problems, wholes that outdo their parts
Each specialist is a small evolved circuit repeated across a grid, inspired by the cortex without copying it: one template, many behaviors, depending on how it gets wired in. The roadmap lets these substrates grow and adapt like living tissue rather than sit as fixed graphs, so a network can develop and keep changing after it is born.
Lifelong
Freeze and reuse: settled specialists stay fixed while new tasks only add coordination, a path to learning across a lifetime without forgetting
For a new task the specialists stay frozen and only the coordination evolves, so hard-won skills are reused instead of retrained. That is the road to learning across a lifetime without overwriting the past. The honest status: today's composition is still task-specific, but the signal for something more general is already there in the population, and pulling it out into genuine emergent reasoning is the open problem I am on.
Will be public upon publication
Active Research Direction
Networks that are grown rather than trained never see human data, so what they do has no obligation to resemble anything we would recognize. I study that on its own terms. The open problem is telling behavior that is genuinely new from behavior that only looks new to us, because every measure we have is calibrated on human data.
PhD Thesis
Grow a big network from a tiny recipe, the way DNA grows a body. It never worked in practice. My thesis diagnoses why, then redesigns it to run at real scale.
Master's Thesis
Built zero-shot conversational AI using sub-knowledge graphs. It proved to me that engineering creates brittle intelligence.
Bachelor's Thesis
Built anonymous, decentralized data sharing right through the browser. It taught me that distributed systems stand or fall on trust.
Pre-Undergrad Research
Watched brains fuse conflicting senses into truth. My first proof that intelligence comes from integrating senses rather than selecting one.
