Dawn Zimmer
Federal Leadership
Dawn Zimmer helps steer the vast digital enterprise of the Department of Energy, where cutting-edge science, clean energy innovation, and national security converge. She stepped into the role of deputy CIO at the end of the Biden administration, and since then, has played a key role in stabilizing the department’s IT leadership as several CIOs have come and gone. As such, Zimmer is responsible for translating the complexity of DOE’s diverse missions into clear technology priorities — modernizing IT infrastructure, strengthening cybersecurity, and advancing cloud and AI adoption across national labs and offices.
