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.

We rely on our members to help us recognize excellence in the field. If you know a colleague doing outstanding work in crystallography, we encourage you to submit a nomination for next year’s awards. Your voice helps shine a light on the achievements that shape our community.
