Liam Fedus is Co-Founder and Co-CEO of Periodic Labs. Before founding Periodic, Liam was Vice President of Research at OpenAI, where he led the post-training team and was a co-creator of ChatGPT. He also co-developed Switch Transformers, groundbreaking research that showed how neural networks could scale beyond a trillion parameters while using computing resources more efficiently, an important advance in the development of more powerful AI systems.

Periodic Labs

Periodic Labs is a frontier research lab building autonomous systems and robotic laboratories designed to accelerate scientific discovery. Unlike most AI models, which learn primarily from existing human-generated data, Periodic’s systems can generate new scientific data through physical experimentation. Its AI analyzes existing research, proposes hypotheses, directs robots to run experiments, and learns from the results, including experiments that fail. Periodic ultimately aims to speed the discovery of new materials across fields including energy, semiconductors, aerospace, and advanced materials, with the near-term goal of discovering a high-temperature superconductor.
