The American Crystallographic Association proudly recognizes three outstanding scientists whose work is advancing the frontiers of structural science:

• David G. Rognlie Award – Dr. Yifan Cheng (UCSF): For transformative innovations in cryo-electron microscopy, including motion correction algorithms and atomic-resolution structures of membrane proteins like TRPV1. His work helped launch the "Resolution Revolution" and continues to drive the field forward.

• A.L. Patterson Award – Dr. Randy J. Read (University of Cambridge): For pioneering likelihood-based methods in macromolecular crystallography, including the development of σA maps and Phaser software—tools now central to modern structure determination.

• Margaret C. Etter Early Career Award – Dr. Emmanuel Nji (CRID, Cameroon): For groundbreaking work on membrane transporters and leadership in building structural biology capacity across Africa through BioStruct-Africa.

Each year, the American Crystallographic Association honors individuals who are pushing the boundaries of structural science. In this post, we’re thrilled to introduce the 2026 ACA Award winners—three exceptional scientists whose innovations and leadership are making a global impact. These awards will be formally presented at the IUCr2026 Congress in Calgary; details of the ceremony will be announced in the coming months.

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?

The professional world abounds with awards and honors designed to highlight specific scientific achievements, but the Fellows program is different. ACA Fellows are characterized as "scientific ambassadors" serving to advance the much broader goals of "scientific education, research, knowledge, interaction, and collaboration." Back when I was a student, my first inkling that science was more than just a single person "making discoveries" came when I started to realize that I needed collaborators. It was years before I fully appreciated all the elements that are required for science to advance and I'm still learning. Science is far more collaborative than I expected: experts with complementary skills must connect and build mutually beneficial relationships. New techniques need to be popularized and made accessible. Complex discoveries need to be communicated clearly and compellingly to engage the public and persuade policymakers of the value of long-term investments in science and education, despite their difficult-to-measure impact. Young scientists need opportunities to participate in and become part of a community ... and to understand the value of doing so.
