The American Crystallographic Association proudly announces the Class of 2025 ACA Fellows—an exceptional group of scientists whose groundbreaking research, impactful teaching, and dedicated service have shaped the field of crystallography and structural science in profound ways. This year’s honorees represent a remarkable spectrum of contributions, from advancing foundational methods and developing revolutionary technologies to championing education, mentoring, and equity across the global scientific community.

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.

Spring is coming soon! Every year, on the 1st of April, the ACA collects nominations for its Fellows program. When I was elected a 2021 ACA Fellow, to be honest, I hadn’t put much thought into why professional organizations bother to make such distinctions. Certainly, being elected a Fellow is an honor and welcome recognition for any individual, but why do we, the ACA, The Structural Science Society, promote this type of recognition?
