Meet Some of AIChE’s Newly Elected Fellows

The rank of Fellow is AIChE’s highest grade of membership and is achieved only through election by the Board of Directors. Nominated by their peers, candidates for AIChE Fellow must have significant chemical engineering experience (generally 25 years), must have demonstrated significant service to the profession, and must have been a member of AIChE for at least 10 years.

Here are some of the recently elected Fellows. More Fellows will be introduced in future issues of CEP and here on ChEnected.

David E. Block

David E. Block is the Marvin Sands Department Chair in Viticulture and Enology at the Univ. of California, Davis, where he holds the Ernest Gallo Endowed Chair. His research has addressed fermentation optimization methods and metabolic engineering of yeast for improved wine production, as well as recent work on single-plant resolution irrigation sensing and control. He played a key role in designing the UC Davis LEED Platinum Teaching and Research Winery. He gained early experience working on process development and manufacturing of biopharmaceuticals at Hoffmann-La Roche. He has also been a leader of AIChE’s Food, Pharmaceutical, and Bioengineering Div.
