MoleculesCrystallography applies to many scientific disciplines

X-ray crystallography is now playing a steadily increasing role in fields such as structural chemistry, protein engineering, drug design, materials science, the study of gases, liquid crystals, minerals and polymers, and the rapid development and utilization of synchrotron radiation, neutron, and electron diffraction facilities. 


Crystallography is relevant to any scientist dealing with molecules, including chemists (structure, function, energetics, mechanism), biologists (as biochemists and enzymologists interested in structure and function), material scientists (nanotechnology), bioengineers, mathematicians (theory of packing, scattering, statistics), minerologists, physicists (scattering, both theory and measurement, and assignment of electrons to nuclear centers) and pharmaceutical drug discovery (materials development).

ACA Fellows Program

 The membership voted to approve the Fellows Program in the 2009 Annual Elections.  Over the past sixty years, the ACA has established ten individual awards to recognize and honor outstanding scientists who have made seminal contributions in research, science policy, and outreach to the general public. Each of these awards recognizes contributions within a specific set of criteria, and in general, are only awarded once every three years. After extensive discussion over the past three years, the ACA Council wishes to establish a fellows program. It will not only recognize a high level of excellence in scientific research, teaching, and professional duties, but also their service, leadership, and personal engagement in the ACA and the broader world of crystallography and science. The ACA Fellows program will celebrate the excellence of our own members from within the ACA, and promote their recognition world-wide to constituencies outside of the ACA, such as their employers, other scientific societies, and the government. ACA Fellows will serve as scientific ambassadors to the broader scientific community and the general public to advance science education, research, knowledge, interaction, and collaboration. It will allow us to significantly recognize and honor a broader cross-section of the membership than is currently possible. We envision that eventually about 5% of the membership will be recognized as ACA Fellows, and will announce new inductees and honor all ACA Fellows at the Awards Banquet each year at our national meetings.  Click here for list of ACA Fellows
