EXPERIENCE

I have over 25 years of experience in structural design and analysis of steel I-girder, steel box girder, steel truss, prestressed concrete girder and post-tensioned bridges, retaining wall, noise wall, and railroad bridges. I was working on some well-known long span bridges, such as Lion’s gate bridge and Paseo bridge. I have written 300 technical papers published, presented accepted or to be submitted to ASCE Journals, ASCE periodicals, conferences, and seminars. I am a Program Manager and Team Leader for IDOT bridge inspections. I was a bridge department manager and PM for 7 years in the past.
