The rank of Fellow is AIChE’s highest grade of membership and is awarded through election by the Board of Directors. Candidates are nominated by their peers and must have significant chemical engineering experience (typically 25 years), demonstrated service to the profession, and at least 10 years of AIChE membership.
Here are some of the recently elected Fellows, with more to be featured in future issues of CEP.
David am Ende
David am Ende is the President of Nalas Engineering — a contract development and manufacturing organization (CDMO) for pharmaceutical and fine chemical customers and a manufacturer of critical chemicals for the U.S. government — responsible for day-to-day operations. His expertise focuses on process safety, reaction engineering, and crystallization engineering. Ende has contributed to the field by presenting and chairing sessions in the Process Development Div. (PDD) and the Pharmaceutical Discovery, Development and Manufacturing Forum (PD2M) at numerous AIChE annual meetings. He also presents regularly at his alma mater, the Univ. of Iowa’s AIChE student chapter.
