BATON ROUGE, LA – The LSU College of Engineering recently held its third Evening of Engineering Excellence at the LSU Faculty Club on April 16, inducting several new members into its Society for Engineering Excellence and Hall of Distinction.
“The Evening of Engineering Excellence is when we come together once a year and celebrate a circle of people who have had a large, lasting impact on LSU Engineering, Louisiana and the world,” LSU College of Engineering Dean Vicki Colvin said. “The people we honor create ripples we feel for years, the ones who make lasting contributions to the college, the university, and our Louisiana family. They have built fields, companies, and communities, and have made our lives easier or safer. They’ve dreamed up new machines, new materials, and new ways to build and create. The college is honored to induct these businesses and individuals into its Society for Engineering Excellence and Hall of Distinction.”
Society for Engineering Excellence
Founded in 2008, the Society for Engineering Excellence recognizes the support of the college’s alumni and friends whose philanthropy creates a difference in the lives of LSU Engineering students and faculty. Over the last 19 years, the college has inducted 69 individuals, corporations, and foundations into the society, each of which has made a significant philanthropic commitment to advance engineering education at LSU.
Going into the SEE this year were DSLD Homes, Cajun Industries, ISC, and LEMOINE.

David Zimmer
David Zimmer is an LSU Engineering grad having earned his chemical engineering degree in 1982. Just a few days after graduation, he was hired on with Union Carbide Corporation, where he worked for 19 years in a variety of manufacturing operations and project roles across three different business areas. When Dow acquired Union Carbide in 2001, Zimmer continued to work for them for another 16 years, again rising as a leader and working in production and project roles across the Gulf Coast.
By the time he retired from Dow, Zimmer was overseeing $5 billion in assets in 10 locations across the globe and led the company’s intellectual property program for its manufacturing operations. Zimmer’s dedication to process safety and industry collaboration earned him the American Chemistry Council Responsible Care Employee of the Year award in 2017.
After retirement, Zimmer developed the chemical engineering department’s student co-op program at LSU, then expanded those concepts to the entire College of Engineering. In this role, he helped prepare hundreds of students each year to land full-time engineering roles after graduation by providing resume advice, prepping students for interviews prep, and identifying industry coop and internship roles. By the time he retired from this role in 2025, nearly 95% of chemical engineering seniors were graduating with manufacturing experience, and full-time hiring of chemical engineering students increased from 60% to 95% in just two years.
