The 73rd ACA Annual Meeting

July 7- 11, 2023 | Baltimore, Maryland

We are delighted to extend an invitation for you to attend the 73rd annual meeting of the American Crystallographic Association which will be held from Friday, July 7th to Wednesday, July 12th, 2023 as a fully in-person meeting. Scientists interested in biological, chemical, and material structures will travel to the waterfront in Baltimore, MD. This year’s meeting will again cover a broad array of structural topics such as quantum crystallography, structural genomics, artificial intelligence and machine learning, MicroED, structure based drug design, the future of light sources, and many more. ACA values the contributions of its members from all backgrounds and we are excited for the addition of a DEI focused session to this year’s program. We welcome all young scientists to our community and will be hosting a career panel for early career scientists, a Three Minute Thesis competition at ACA2023.

The ACA is proud to offer a number of ways to assist early career scientists including the ACA Travel Grant Program, Poster Prizes and opportunities to present.  


The meeting will convene at the Baltimore Marriott Waterfront.  Experience everything Charm City has to offer. The Baltimore Marriott is situated on the waterfront in the Harbor East neighborhood, offering unparalleled access to Fells Point, the National Aquarium and the restaurants and shops of the Inner Harbor.  Find out more about our venue...
