Patrick Riley, Ph.D.


I’m a Phan. I’ve been to more than 30 Phish shows. I love the spontaneity, variety, energy and the other fans. Some of the best shows have been on the beach in Mexico, but I think my son is going to be disappointed with all future concerts where you can’t dance in the ocean.

Patrick Riley leads the artificial intelligence group at Relay Therapeutics, applying learning methods to the discovery process. He has over 15 years of data science and machine learning experience. He came to Relay Therapeutics from Google, where he was a principal software engineer and a lead of the Accelerated Science team. His work spanned areas as diverse as cell imaging, nuclear fusion and materials science. His most important work was on the application of machine learning to small molecules, including foundational work on graph neural networks and their application to DNA encoded small molecule library screening.

Patrick holds a Ph.D., M.S. and B.S. in Computer Science from Carnegie Mellon University.
