AIChE Structure

In addition to AIChE's Board of Directors, presidents, the Institute operates with leadership from multiple organizational entities. AIChE's three Operating Councils work with all organizational entities to lead the Institute’s efforts to realize AIChE’s Vision:

  • Provide value as the global leader of the chemical engineering profession
  • Be the lifetime center for professional and personal growth and security of chemical engineers
  • Be the foremost catalyst in applying chemical engineering expertise in meeting societal needs

Operating Councils

The 3 operating councils work with all other institute entities and individually dedicate themselves to Career and Education, Chemical Engineering Technology, and Societal Impact. They work with the various entities that make up AIChE—divisions, forums, committees, local sections, and student chapters.

Divisions & Forums

20 Divisions and Forums focus on the technical areas in which chemical engineers work, including advanced materials, biotechnology, computational molecular science, education, energy, nanoscience, particle technology, process development, safety and health, sustainability, and many more.

Local Sections

There are more than 110 Local Sections throughout the United States and Puerto Rico, plus The Netherlands, Belgium, Saudi Arabia, Singapore, and Canada. Sections sponsor activities of interest to members in their particular area and are the grassroots of AIChE.


23 National Committees work to further the objectives of the institute, both internally and through outreach efforts. Examples include committees dedicated to awards, ethics, equipment testing procedures, government relations, professional development, and women's initiatives.

Student Chapters

There are more than 160 student chapters and Student Clubs on campuses in the United States, Puerto Rico, Mexico, Canada, Nigeria, and Hong Kong, offering undergraduates a chance to learn more about their chosen profession. As AIChE grows, new international student chapters are created every year.

Technological Communities

Technological Communities allow industry, academia, and government representatives to collaborate and leverage resources for research and technology transfer. These communities include the Center for Chemical Process Safety (CCPS), the Society for Biological Engineering (SBE), the Center for Energy Initiatives (CEI), the Institute for Sustainability (IfS), and the Design Institute for Physical Properties (DIPPR).
