March 2022: Exploring Structural Database Use in Crystallography: Workshop Series

The U.S. National Committee for Crystallography (USNC/Cr) of the National Academies of Sciences, Engineering, and Medicine is providing an online workshop series for students and researchers on the use, development, and maintenance of crystallographic and structural databases. Encompassing macromolecular, small molecule, and powder diffraction information, the series will include 11 modules each meeting for one or two days.

Graduate students, postdoctoral fellows, faculty members and researchers in any of the crystallographic, diffraction, and imaging sciences affiliated with the International Union of Crystallography (IUCr) are encouraged to register and participate in the training sessions that interest them.

Registration for this online series is free. To register, please visit: The details about each session can be found by clicking the event pages along with a registration link allows one to register for any combination of the sessions. 

Undergraduate students with appropriate research experience will be considered.
