The ACA is proud to celebrate a major milestone in the career of Dr. James Kaduk, who has been elected a Fellow of the American Association for the Advancement of Science (AAAS)—one of the highest distinctions in the scientific community.

Jim’s impact on crystallography, particularly in the field of powder diffraction, is well known to our members. But beyond his scientific achievements, Jim has been a pillar of the ACA for years—a generous colleague, dedicated mentor, and tireless advocate for crystallographic education and outreach.

This honor recognizes not only Jim’s technical contributions, but also his deep service to the broader scientific community. Through his leadership roles, educational efforts, and willingness to guide and support others, Jim has helped advance not just data and methods—but people.

AAAS Fellowships are awarded to individuals whose work has made a meaningful difference in science and society. We can think of no one more deserving. From all of us at the ACA: Congratulations, Jim! We’re proud to call you one of our own.
