2024 Awardees & Plenary Sessions

We are excited to honor three outstanding individuals who have made significant contributions to the field of structural science at this year’s annual meeting. Driven by their passion for advancing scientific understanding, these awardees have demonstrated excellence in research, innovation, and leadership. Join us in celebrating the remarkable achievements of these individuals, as they inspire and shape the future of structural science.

Margaret C. Etter Early Career Award: BENJAMIN FRANDSEN

Tuesday, July 9 2024 @ 11:45 AM MT

Established in 2002, the Margaret C. Etter Early Career Award has recognized a long list of awardees who have exhibited outstanding achievement and exceptional potential in structural science research demonstrated by a scientist at an early stage of their independent career. This year Benjamin Frandsen will be receiving this award for his pioneering developments, both theoretical and experimental, of the novel magnetic pair distribution function (mPDF) method for studying short-range magnetic correlations in ordered and disordered magnetic systems, and for his outstanding leadership, mentorship and service to the community. We are thrilled to recognize the outstanding achievements of Benjamin Frandsen, while also spotlighting his remarkable leadership and dedication to the community.

M.J. Buerger Award: THOMAS ALBRECHT-SCHOENZART

Wednesday, July 10, 2024 @ 11:45 AM MT

M.J. Buerger was a mineralogist who made major contributions to many areas of structural science and this award, in his name, was established to recognize mature scientists who have made contributions of exceptional distinction. In Denver, Colorado we will bestow this award on Thomas Albrecht-Schoenzart. Mr. Albrecht-Schoenzart is a prolific solid-state inorganic chemist who is transforming our understanding of the periodic table through his structural studies of f-block elements. His studies of the structure and bonding in radioactive heavy element compounds have expanded our understanding of the f-block elements and redefined the chemistry of the actinide elements and even the periodic table. We look forward to celebrating Thomas Albrecht-Schoenzart’s remarkable achievements and acknowledging the vital role he has played in advancing structural science research.

Bertram Eugene Warren Diffraction Physics Award: JOHN GREEDAN

Thursday, July 11, 2024 @ 11:45 AM MT

The Bertram Eugene Warren Diffraction Physics Award is awarded to outstanding scientists to recognize important recent contributions to the physics of solids or liquids using X-ray, neutron, or electron diffraction techniques. This year we will celebrate John Greedan with this prestigious award at the 74th annual American Crystallographic Association meeting in Denver, Colorado. Mr. Greedan has made tremendous contributions to the research on structure-property relationships in perovskites and pyrochlores. In particular, his body of work on pyrochlores has had an immense impact on the field, making him one of the most influential researchers in this area. He has used neutron diffraction elegantly for both crystal structure and magnetic structure determination. His papers “Magnetic Pyrochlore Oxides” (Rev. Modern Phys. 2010, 82, 53) and “Geometrically frustrated magnetic materials” (J. Mater. Chem. 2001, 11, 37) are highly revered in the field and have been cited thousands of times. Join us in congratulating John Greedan on this well-deserved achievement, in Denver in July of 2024, as we celebrate his remarkable accomplishments in the realm of diffraction physics.
