BIO
Before b-12, Andres built the first AI agent to plan and make molecules in a robotic lab (750+ cites in Nature Machine Intelligence, and Best Paper at NeurIPS AI for Science), along with several other works in agents and LLMs for chemistry (1100+ citations). He was an Intern at Max Planck (Math in Science), and PhD at EPFL (AI+Chemistry). Automation is the future of chemistry, but integration and human operability is the hidden demon nobody talks about. We're fixing that at b-12.
Ex-company, school and discipline below are derived from this bio. Nothing is inferred when the bio is missing.
