Research and Interests:

Professor David Trejo's research focuses on the design and development of materials and systems for efficient construction processes and products. His interests focus on the design and development of systems that allow for accelerated and durable construction. Specific research projects have included development of precast overhang systems for safe, rapid, and durable bridge construction, assessment and modeling of segmental, post-tensioned bridges exhibiting strand corrosion, development of refractory materials for NASA’s launch complex, modeling and performance assessment of glass fiber-reinforced polymer (GFRP) concrete reinforcement, and many others. His teaching interests include heavy civil construction methods and processes, cementitious materials and systems, rapid and durable construction. With almost 10 years of experience in the field, Dr. Trejo brings real-world applications into the classroom.
