About the school

The International School on Fundamental Crystallography, a series of educational schools in Latin America, commenced seventeen years ago at the University of Havana, Cuba, and has been hosted biannually in various countries across the region, including Havana, Cuba, Montevideo, Uruguay, Uberlândia, Brazil, La Plata, Argentina, and Bogota, Colombia. The school has served as an important space for the training of Latin American graduate students in the field of crystallography.


The VII edition of the school, set to take place in Lima, Peru, in 2020, was postponed due to the global COVID-19 pandemic. Consequently, at the request of the Peruvian academic community, the Commission on "Mathematical and Theoretical Crystallography" of the International Union of Crystallography (IUCr) granted the Faculty of Physical Sciences at the Universidad Nacional Mayor de San Marcos in Lima, Peru, the opportunity to organize the International School on Fundamental Crystallography: Seventh MaThCryst School in Latin America, from August 12 to 16, 2024.

The school, designed for students from the region, aims to bring together crystallographers from various countries and promote graduate studies in this scientific field. Since its first edition, the school has experienced steady growth in the number of participating Latin American professors and students, thanks to financial support from important institutions such as the IUCr, CLAF, and other regional universities. It is noteworthy that this event has already been recognized as an official school of the IUCr.

Language

The official languages of the school are English and Spanish. Some classes will be taught in English, however the presence of Spanish-speaking tutors familiar with the classes beforehand will provide assistance to those who need it by translating or answering questions on the subject.

Gender Equity and Diversity Policy

Herewith, we the organizers of International School on Fundamental Crystallography. Seventh MaThCryst School in Latin America endorse the IUCr GEDC Code of Conduct.

 

Statement on Gender Balance at International School on Fundamental Crystallography. Seventh MaThCryst School in Latin America.

The International School on Fundamental Crystallography. Seventh MaThCryst School in Latin America Organizing Committee fully supports and promotes gender equality in accordance with the IUCr policy https://www.iucr.org/iucr/principles-and-policies/gender-balance.

We will ensure gender equality in our committees (including the Organizing Committee itself), among our lecturers and participants and pay special attention to the gender balance in evaluating bursary applications.

Our gender statistics on female participation in the schools conducted are shown in the following graph. In this context and in accordance with IUCr policies and according to the observed behavior, in the present school we will emphasize female participation. For further information, our gender equity and diversity advisor is MSc. Maria Luisa Cerón Loayza (e-mail: mceronl@unmsm.edu.pe).


Further information can be found on the web site of IUCR’s Gender Equity and Diversity Committee GEDC (https://www.iucr.org/iucr/governance/advisory-committees/gedc). This page contains a code of conduct, a GEDC conference speaker statement and a toolkit for conference organizers.
