# Geoffrey Fairchild, Ph.D.

> Personal homepage for Geoffrey Fairchild, Ph.D. — AI/ML researcher and national security leader based in 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.

My focus is turning AI research into capabilities that advance national security, while building the teams and partnerships needed to deliver them.
