Geoffrey Fairchild, Ph.D.

Santa Fe, New Mexico, USA

With over a decade at Los Alamos National Laboratory, I grew as a computer scientist into a leader, building the science and tools to meet critical national security challenges.

Now, as Deputy Director of LANL's National Security AI Office, the work is broader and more consequential: shaping Lab-wide AI strategy, managing partnerships across the DoD, IC, industry, and academia, and making sure our technical capabilities align with what the mission actually needs. Along the way, leading a group of about 100 researchers taught me that great leadership means caring as deeply for the people doing the work as for the purpose driving it.

What I'm here for: cutting-edge science and AI in service of problems that actually matter.
