Over 20 years of experience in the post-tensioning field and other structural areas covering American building codes as well as international codes with a focus on research & development, structural design, repair and strengthening, process set up, and training programs. Responsible for designing new bonded and unbonded post-tensioning systems with various filed patents. Have been teaching for several years Prestressed Concrete for both pre-tensioning and post-tensioning.  

Involved in several committees at ACI (American Concrete Institute), PTI (Post-Tensioning Institute), and fib (International Federation of Concrete). Currently serving as the Chair of ACI 320 which is an upcoming building code for post-tensioning, member of ACI 318, Chair of PTI Building Design Committee, and a member of PTI Technical Advisory Board.
