Occupational Ergonomics and Biomechanics (OEB) Laboratories
Our Motto
UT PROSIM THAT I MAY SERVE
Welcome to the Occupational Ergonomics and Biomechanics Laboratories
The Occupational Ergonomics and Biomechanics (OEB) Laboratories conduct work in theoretical and applied ergonomics, occupational biomechanics, and work physiology, primarily relating to worksite, workstation, and equipment evaluation and design. Specifically, research is focused on:
- Biomechanics of the human body (modeling, strength, motions, and working postures);
- Human engineering of systems, equipment, tools, workstations, and work tasks;
- Ergonomic design for safety, efficiency, and performance.
Major application domains for the work in the laboratories are manufacturing, construction, and healthcare. The Laboratories consist of several rooms, which are used as needed for research, development, and evaluation. Those Laboratories are well equipped to do research in a variety of areas.

Thrilled to share that two of the OEB Labs' Ph.D. students, Feyisayo "Fehi" Akinwande and Mohamad Behjati Ashtiani, have successfully defended their dissertations! Your hard work and dedication have paid off — wishing you both continued success in your careers. 🎉 (February 2026)
OEB Lab graduate student Feyisayo Akinwande (advisor: Dr. Maury Nussbaum) successfully defended his dissertation, "Assessing the Effects of Exoskeletons on Physical Demands, Trip and Slip Risks, and User Perceptions in Manual Mining Tasks." He has transitioned into an industry role, working as an EHS Ergonomics Specialist at Amgen North Carolina since December 2025. Congratulations, Dr. Akinwande! (February 2026)
OEB Lab graduate student Mohamad Behjati Ashtiani (advisor: Dr. Maury Nussbaum) successfully defended his dissertation, "Musculoskeletal Modeling of Back-Support Exoskeletons: Comparative Evaluation of Spine Loads, Muscle Activity, and Optimization Strategies." Congratulations, Dr. Behjati Ashtiani! (February 2026)
