An internationally recognized expert in structural engineering and inductee to the National Academy of Engineering (NAE), Dr. Poston has established himself as one of the preeminent structural consultants in the United States. Dr. Poston has authored and delivered hundreds of papers and presentations related to the structural engineering industry and championed the repair of existing structures for upwards of 30 years. He readily relates that he has never met a structure that cannot be repaired and has dedicated his career to advancing the state of structural engineering knowledge.

As past Chair of the American Concrete Institute (ACI) Committee 318 Structural Building Code (2008-2014), Dr. Poston oversaw a monumental effort to completely reorganize the concrete code, the first undertaking of its kind in the history of ACI. Engineering News-Record (ENR) named him a "Top 25 Newsmaker" of 2014 for his code reorganization leadership and ACI bestowed him with the Henry L. Kennedy Award for "...outstanding technical and administrative leadership in guiding ACI Committee 318 through the arduous and largely unique process of reorganizing the ACI Building Code Requirements for Structural Concrete." The same year, one of his repair projects, Courthouse Square Complex Renovation, received the ICRI Award of Excellence. This marked consecutive years of receiving the award, as the Houston Hobby Airport Parking Structure was honored in 2013. Other past projects led by Dr. Poston that received recognition include the Champion International Parking Structure Repair in Stamford, CT (2000 ICRI Award of Excellence), Marina del Rey Sea Wall Repair in Los Angeles (2002 ICRI Project of the Year), and the Solomon R. Guggenheim Museum Exterior Restoration Project in New York (2009 ICRI Award of Excellence).

Dr. Poston earned a Ph.D. in Structural Engineering in 1984, a Master of Science in Structural Engineering in 1980, and a Bachelor of Science in Civil Engineering, With Highest Honors, in 1978, all from the University of Texas at Austin. In 2014, Dr. Poston was selected as a Distinguished Engineering Graduate of The University of Texas at Austin Cockrell School of Engineering. This followed being elected to the Academy of Distinguished Graduates at The University of Texas at Austin Department of Civil, Architectural and Environmental Engineering in 2008.

When not working on projects or volunteering time for committee work, he enjoys traveling with his family. His many colleagues know he is always in search of the "perfect" cup of coffee.
