ACA Meeting Policies

ACA meetings are open to ACA members and those interested in crystallography.  The ACA is committed to providing a safe, productive and welcoming environment for all meeting participants and ACA staff. All participants including, but not limited to, attendees, speakers, volunteers, exhibitors, ACA staff, service providers and others are expected to abide by the following policies.  


Diversity Statement

The American Crystallographic Association is committed to diversity and inclusiveness in our membership, as well as in all activities, events, and programs, and services. Scientific innovation requires bringing together both diverse ideas and people from varied backgrounds who may have different world views and ways of solving problems. The ACA seeks to include and engage members across age, gender identity and expression, race, nationality, ethnicity, physical ability, marital status, sexual orientation, socioeconomic status, military or veteran status, or any other facet of social diversity in our society and seeks to remove obstacles to their professional growth and advancement. Through our actions at the international, national, and local levels, we strive to promote inclusion in academic, industrial, and government institutions for both current and future members of our organization.


Conference Policy

The ACA recognizes the positive impact that a conference speaking opportunity has on an individual's track record and visibility. We also recognize that some sections of the scientific community are often under- represented in conference programs, and that this can affect diversity in the long-term. Our policies were developed to ensure quality and equality.

Speaker Invitation Policy

The program chairs will ensure the highest quality scientific program, with speakers that represent the broad diversity of our community. We aim to achieve a speaker and program chair balance that reflects the make-up of our community without bias with regard to gender identity or expression, sexual orientation, race, religion, geography, disabilities, or national origin.

Reporting Policy

We will report statistics on the conference website on the geographic and gender balance of invited speakers, selected speakers, session chairs, and attendees.


Code of Conduct Policy

The ACA Meeting is an annual event providing scientists from a wide variety of backgrounds the opportunity to exchange cutting edge ideas and techniques in multiple areas of research. Each meeting highlights various aspects of crystallography and demonstrates their significance to the greater scientific community. ACA is committed to providing a safe, productive, and welcoming environment for all meeting participants and ACA staff. All participants, including, but not limited to, attendees, speakers, volunteers, exhibitors, ACA staff, service providers and others are expected to abide by this ACA Meetings Code of Conduct.

  • Anyone experiencing or witnessing behavior that constitutes an immediate or serious threat to public safety is advised to contact 911 and locate a hotel house phone and ask for security.

IUCr Scientific Freedom Policy Statement

The ACA is excited to partner with the IUCr in funding student travel to the 2019 Annual Meeting!

The Organizing Committee of the American Crystallographic Association 2019 Annual Meeting shall observe the basic policy of nondiscrimination and affirms the rights of scientists throughout the world to adhere or to associate with international scientific activity without restrictions based on nationality, race, color, age, religion, political philosophy, ethnic origin, citizenship, language, or sex, in accordance with the Statutes on the International Council for Science. At this meeting no barriers will exist which would prevent the participation of bona fide scientists.
