The American Institute of Chemical Engineers (AIChE) is a professional organization for chemical engineers. AIChE was established in 1908 to distinguish chemical engineers as a profession independent of chemists and mechanical engineers.
As of 2013, AIChE had over 45,000 members, including members from over 100 countries worldwide. Student chapters at various universities around the world have also been established throughout its history. The student chapters tend to focus on providing networking opportunities in both academia and in industry as well as increasing student involvement locally and nationally.
