College recognizes 12 exceptional alumni
An entrepreneur building the future of autonomous logistics, a civil engineer who helps protect drinking water for millions and a leader who oversees Ford’s best-selling F-Series truck franchise are among the 12 alumni honored during the 2024 College of Engineering Alumni Awards on October 25.

The celebration recognizes alumni from across the College of Engineering who have achieved distinction in their fields or through their extraordinary service contributions since graduating from The Ohio State University.
“I’m continually inspired by our alumni award winners’ stories and how they’ve leveraged their Buckeye experience to build success while making outstanding contributions in their disciplines,” Dean Ayanna Howard, the Monte Ahuja Endowed Dean’s Chair, shared with distinguished alumni and their guests.
Three distinguished alumni from the Department of Civil, Environmental and Geodetic Engineering were among the evening's honorees.

Daniel G. Linzell (BS ’90, civil engineering) received the Distinguished Alumni Award for Academic Excellence. Prof. Linzell is the associate dean for graduate and international programs and the Leslie D. Martin Professor of Civil and Environmental Engineering at the University of Nebraska-Lincoln. He is on loan to the National Science Foundation where he directs their Division of Civil, Mechanical and Manufacturing Innovation, whose annual research budget is over $220 million.

Deborah H. Lee (BS ’84, MS ’86, civil engineering) was recognized with the college's Distinguished Alumni Award for Career Achievement. Ms. Lee has spent her 39-year career with the U.S. Army Corps of Engineers and the National Oceanic and Atmospheric Administration (NOAA), driving innovative federal water resources management and research, preserving vital infrastructure, preventing billions in flood damages, protecting drinking water for millions, and restoring, connecting and conserving lands and waters.
During their visits to campus, Lee and Linzell shared stories of their respective, professional journeys during seminars attended by CEGE students, faculty and staff. Ms. Lee recounted her experiences implementing projects such as a joint plan between the United States and Canada to regulate Lake Ontario and recommended opportunities for students to obtain technical and leadership skills at various points in their future careers in engineering.
Prof. Linzell discussed how "stepping forward" to engage new experiences broadened his horizons, both personally and professionally. He emphasized the importance of fostering collaboration and creating meaningful impact for the public who benefits from civil engineering research and practice.

Phuthuma Freedom Nhleko (BS ’83, civil engineering) was also honored with the Distinguished Alumni Award for Career Achievement.
