This episode spotlights Alabama Turfgrass Association member Dr. David Han

For more than two decades, Dr. David Han has been a steady and influential presence in Alabama’s turfgrass industry. As an Associate Professor and Turfgrass Specialist for Extension at Auburn University, Dr. Han has dedicated his career to advancing turfgrass education, supporting industry professionals, and mentoring the next generation of leaders. His work through the Alabama Cooperative Extension System and the Alabama Turfgrass Association (ATA) continues to leave a lasting mark across the state and beyond.

Roots in Science and a Path to Turfgrass

Dr. Han grew up in Urbana, Illinois, and pursued his undergraduate and master’s degrees at Cornell University before earning his Ph.D. from The Ohio State University. With a bachelor’s degree in biology, his early academic path was rooted firmly in the sciences. It was during his time at The Ohio State University that Dr. Mike Boehm, his postdoctoral advisor, helped point him toward the turfgrass industry—a direction that would ultimately shape his career.

Along the way, he was influenced by some of the most respected minds in turfgrass, including Dr. A.J. Powell, Dr. Mike Goatley, and several outstanding superintendents such as Todd Voss and Mark Yoder. Their professionalism and approach to the craft demonstrated what it truly takes to excel in turf management. Closer to home, Dr. Han credits numerous Alabama turf professionals as role models, singling out James Horton as “standing out among the standouts.”

A Career Built on Service and Education

Dr. Han began his tenure at Auburn University in 2000 and has since worn many hats—educator, researcher, Extension specialist, and industry leader. In addition to his academic responsibilities, he serves as Educational Director for the ATA and the Deep South Turf Expo, helping shape high-quality programming for turf professionals across the region.

There is no such thing as a “typical” day in his role. One day may involve teaching university students; the next, visiting a golf course, baseball field, or sod farm; and another, leading a workshop or speaking at an industry event. This variety is part of what makes his work meaningful.

What does he enjoy most? Simply put: helping people do their jobs better. Whether that means diagnosing a turf issue, interpreting data, or providing practical guidance, Dr. Han is passionate about being a resource for the industry. The greatest challenge, he admits with a smile, is time—there is always more to do (and ATA is always asking for something!).

Among his proudest accomplishments are the many successful graduates who have come through Auburn’s turf program and are now thriving in their careers. Seeing former students excel in the field is, for him, one of the most rewarding aspects of his work.

Industry Evolution and Perspective

Since starting at Auburn, Dr. Han has witnessed significant changes in the turfgrass industry. The introduction of automated equipment—drones, robotic mowers, and advanced data systems—has transformed operations. While these tools offer tremendous opportunity for precision and efficiency, he cautions that data is only as valuable as the understanding behind it. “It could be good or bad if you don’t know what the data is telling you,” he notes.

Looking ahead, he sees both challenges and opportunities for turf professionals in Alabama. Technology continues to advance, expectations continue to rise, and environmental stewardship remains critical. For those just starting out in the industry, his advice is simple but powerful: stay curious, stay connected, and never stop learning.

Commitment to ATA

Dr. Han’s involvement with ATA has been extensive, including his leadership role as Educational Director. Through conferences, workshops, and the Deep South Turf Expo, he has helped elevate educational opportunities for members across the state.

ATA membership, in his view, fosters connection, professional growth, and a shared commitment to advancing the industry. The relationships built through ATA strengthen not only individual careers but also Alabama’s turfgrass community as a whole.

Life Beyond Turf

Outside of work, Dr. Han’s life is centered on faith and family. He and his wife, Tara, have been married for 26 years and are the proud parents of Jacob, 17, who enjoys aviation and gaming, and Laura, 13, who participates in band at East Samford School. Their home is also lively, with four cats (Dr. Han proudly admits he’s a “cat man”).

He is actively involved at Holy Trinity Episcopal Church, where he sings in the choir and has served as backup choir director since last fall. Much of his free time is spent supporting his children’s activities and enjoying the close-knit feel of Auburn—a university town that, despite its growth, still feels like home. The weather doesn’t hurt either.

Looking Ahead

When asked about his goals for the next five to ten years, Dr. Han responds with characteristic humor and heart: “Save the world! Keep people from destroying the world.” At its core, that means continuing to advance Auburn’s turf program, promote responsible management practices, and support the professionals who care for Alabama’s landscapes.

Even as retirement eventually approaches, he hopes to remain connected to the industry that has given him so much. His dedication to education, mentorship, and service ensures that his influence will continue to shape Alabama turfgrass for years to come.

The Alabama Turfgrass Association is honored to spotlight Dr. David Han—a leader, educator, and advocate whose passion for helping others defines both his career and his character.
