Over 25 years of American and international experience in the post‑tensioning field and other structural engineering areas, with a focus on new technologies, product and structural research and development, patenting, structural design, repair and strengthening, process implementation, and training programs. Contributed to the development of new post-tensioned slab systems with fiber concrete, and the development of new bonded and unbonded post‑tensioning systems with multiple patents filed.

Involved in several professional committees at ACI (American Concrete Institute), PTI (Post-Tensioning Institute), and fib (International Federation of Concrete). Currently serving as a member of the ACI Board of Direction, ACI TAC, ACI 318, ACI/PTI 320 (Post-tensioned Structural Concrete Code), and PTI Building Design committee. Notable previous appointments include serving as Chair of ACI/PTI 320‑25, Chair of the PTI Building Design Committee, and member of the PTI Technical Advisory Board. Also, currently serving as a member of JHU Advisory Board for Civil and Systems Engineering CaSE.
