He has built the first scalable neuronal culture platform for biocomputation and validated performance via reinforcement learning on this substrate.\n\n## **🙏** Asks\n\nJoin the team! We're hiring across the stack for neurobiologists, RL researchers, electrical engineers, and biochemists, accepting both direct applications and referrals.
