The rank of Fellow is AIChE’s highest grade of membership and is achieved only through election by the Board of Directors. Candidates for AIChE Fellow are nominated by their peers. Candiates must have significant chemical engineering experience (generally 25 years), have demonstrated significant service to the profession, and have been a member of AIChE for at least 10 years. Meet some recently elected Fellows below. More Fellows will be introduced in future issues of CEP.
