What is PCCr4?

The Fourth Pan-African Conference on Crystallography (PCCr4) is an upcoming event that marks a significant milestone in the field of crystallography across Africa. Set to be held in Algiers, Algeria, in 2025, this conference builds on the success of previous meetings, with the first one kicking off in Cameroon in 2016, followed by events in Ghana in 2019 and Kenya in 2023. PCCr4 aims to serve as a vibrant forum for researchers, scientists, and students from across the continent and around the globe to exchange knowledge, share the latest scientific advancements, and collaborate on the multifaceted applications of crystallography.

Purpose and Goals of PCCr4:

The main purpose of PCCr4 is to advance the field of crystallography in Africa. Crystallography is a foundational science that plays a crucial role in understanding the structures of materials at the atomic or molecular level. This knowledge is essential for a wide range of scientific endeavors, from developing new pharmaceuticals to creating innovative materials and understanding geological formations.

Statement on Gender Balance for PCCr4


At PCCr4, we are dedicated to promoting crystallography across the African continent and ensuring equal opportunities for all participants, regardless of gender. In alignment with the IUCr's policy on gender balance, we have implemented several actions to support and encourage the participation of women in crystallography.

Drawing on the successful initiatives from previous conferences and feedback from organizing committees, we aim to create a program that reflects gender diversity and inclusion. Specifically, our approach includes the following measures :​

  • Plenary Lectures : We will ensure that male and female scientists deliver the plenary lectures;
  • Microsymposia presentations : We strive to achieve at least 50% female representation among the presenters in the microsymposia;
  • Bursary selection : The IUCr criteria for gender balance will be rigorously applied in selecting bursary recipients, prioritizing young scientists attending the meeting.

IUCr Scientific Freedom Policy Statement


The organizing committee of PCCr4 adheres to the fundamental policy of non-discrimination, affirming the right and freedom of scientists to engage in international scientific activities without regard to ethnic origin, religion, citizenship, language, political stance, gender, sex, or age, as per the Statutes of the International Council for Science. We commit to ensuring that no barriers exist at this conference that would prevent the participation of bona fide scientists.

By fostering an inclusive environment, we aim to support and promote the advancement of crystallography in Africa, reflecting our commitment to diversity and equality.
