Call for Abstracts and Early Bird Registration Open Now

Thank you Crystallography Community!

We want to thank and acknowledge all of you who have submitted abstracts to the 26th Congress and General Assembly of the International Union of Crystallography Congress 2023. The enthusiastic response from our global community has met all expectations. We are excited that our goal to create a content-rich programme is coming to fruition.

In light of the multiple requests, we have listened. We have re-opened the Call for Abstracts to allow additional time for those who need it. The submission portal will now remain open until 21 February 2023.

New dates and timelines for the Call for Abstracts can be found here.

We do recognise it is a busy time of year for everyone. For North America, we wish you a very Happy Thanks Giving and for those who celebrate this traditional time of year, we wish you all a very happy season. For our most northern colleagues and friends, we send you our warmest wishes as you head into Winter. Wherever you are in the world, we wish you a safe and happy time for the holiday season.

The extension of the Call for Abstracts deadline will be the final opportunity for you to be a part of the IUCr 2023 program.

Season Greetings,

Professor Michael Parker
Chair, Local Organising Committee
IUCr 2023

Gender equity and diversity

The IUCr is committed to achieving gender equity and diversity (that mirrors our crystallography community) in all its endeavours and activities. A key aspect of the IUCr mission is to ensure our community fosters inclusion, ensures mutual respect, and embraces diversity. To help achieve its diversity goals, the IUCr has developed a code of conduct which applies to all its endorsed or funded activities.
