Tuscaloosa, Ala. — The University of Alabama College of Engineering recently honored six alumni and one friend of the College by inducting them into its 2023 class of Distinguished Engineering Fellows.

Each year, the College of Engineering inducts a select group of alumni and friends as Distinguished Engineering Fellows. Recognition as a Distinguished Fellow is the highest commendation given to graduates and others who have strengthened the reputation of the College of Engineering through their efforts.

Since the recognition’s inception 34 years ago, fewer than 400 individuals have been recognized as Distinguished Engineering Fellows.

The 2023 class includes Steve Cook, of Huntsville; Christine Dedrick, of Madison; Lt. Col. Greg Floyd, of Tuscaloosa; Paul Lammers, of The Woodlands, Texas; Srinivas Mandyam, of San Jose, California; Kenneth Nolen Jr., of Columbiana; and Sid Tankersley, of Sylacauga.

The inductees were honored at a ceremony at Hotel Capstone in Tuscaloosa. For complete biographies of this year’s Distinguished Engineering Fellows, visit the special event page.
