Dr. Stikeleather is works on a multidisciplinary team to develop 'drop-in' transportation fuels from renewable feedstocks.


Dr. Stikeleather, a professor of biological and agricultural engineering at North Carolina State University, was selected for the honor in recognition of his many outstanding accomplishments in industry and academia as a researcher and professor. Throughout his career, he has been involved in the area of machine design and the interaction of machines with their human operators. He spent 16 years in industry with Universal Oil Products Company and Allis-Chalmers Corporation, during which his contributions and service were focused on innovations in operator comfort and safety of agricultural equipment. He was actively involved in standards development at the national and international level in the area of operator whole-body vibration and ride comfort.

Dr. Stikeleather

Stikeleather pioneered and patented a concept for active seat suspension technology, along with an on-board computer control, which allowed the commercialization of active seats on agricultural tractors. His work has received 11 patents in a wide range of topics, including active vibration control for seat suspensions for tractors and construction machinery, rapid extraction methods for bioactive compounds from plant material, and biofuels conversion processes. His current research involves processes for converting renewable oils and fats to "drop-in" transportation biofuels such as bio-gasoline and bio-jet fuel. Funded by the NC Biofuels Center, the project involves the departments of biological and agricultural engineering, mechanical and aerospace engineering, and chemical and biomolecular engineering.

For the past 24 years, Stikeleather has been training tomorrow’s innovative engineers though his outstanding teaching program at North Carolina State University; he is currently teaching Analytical Methods in Mechanical Design and Introduction to BAE Methods. He has authored or coauthored more than 45 refereed journal articles, book chapters, conference proceedings, and technical publications.

Stikeleather has contributed his leadership and expertise to various ASABE Society technical committees, including the Textbooks and Monographs and PE Exam review committees. He was an ASABE Distinguished Lecturer in the tractor design series entitled Operator Seats for Agricultural Equipment.

Stikeleather’s previous awards and honors include a Society of Automotive Engineers Technical Board Certificate of Appreciation in Recognition of Outstanding Contributions to the ASAE Human Factors Committee, an Acoustical Society of America Certificate of Appreciation for Significant Contributions to ANSI Standards, and ASABE Wisconsin Section Engineer of the Year Award. He has been an active member of the Society of Automotive Engineers for more than 40 years and achieved the grade of Fellow.
