Paul Sumitro, Ph.D, P.E., M.B.A is one of the best known and most respected minds in the field of Structural Health Monitoring (SHM) and Non Destructive Evaluation (NDE). Upon his doctoral graduation, he started his career as Structural Design and Analysis Engineer at Japan Structural Engineering and Computation Corp. In 1998 he accepted the position as Chief Engineer at Keisoku Research Consultants (KRC), a company with more than 40 years experience in providing Observational and Informational Construction Support and NDE based Structural Rigidity Assessment Service. Today, KRC maintains 70% of Structural Health Monitoring Systems for bridge structures in Japan, including the world longest suspension bridge, Akashi Kaikyo Bridge and the world longest cable-stayed bridge, Tatara Bridge.

Dr. Sumitro came to United States in 2005 to take the position as the President of Smart Structures. Under his leadership and collaborating with Universities and Research Institutions worldwide, Smart Structures has developed several advanced NDE technologies in SHM such as the Smart Line Imaging Tracer (SLIT) System, magnetic stress sensor, fiber optic displacement sensor and full-field optical scanning sensor. Some of these newly developed technologies are in either patented or patent registration procedures.

Dr. Sumitro is a licensed Professional Engineer in the United States. Besides his career as practitioner in structural engineering he is also very active in professional societies. He is a member of the American Society of Civil Engineers (ASCE), International Association-Fracture Mechanics of Concrete and Concrete Structures (IA-FraMCoS), International Association Bridge Maintenance And Safety (IABMAS), Nuclear Engineers Association (NEA), International Society for Structural Health Monitoring and Intelligent Infrastructures (ISHMII), and the National Society of Professional Engineers (NSPE). Currently, he serves as Chairman of Application Task Group at International Society for Structural Health Monitoring and Intelligent Infrastructures (ISHMII). He has a tremendous world-wide SHM network. Dr. Sumitro got an MBA from University of Illinois at Urbana Champaign.

Dr. Sumitro has led several projects that are directly relevant to the Condition Assessment of Infrastructures using SHM and NDE Methods:

• 1998, Dr. Sumitro led a project to analyze the existing structural rigidity and safety assessment for post tension Chuno Great Bridge in Japan by getting feed-back from field loading test using several types of NDE techniques, such as impact echo, acoustic emission and GPR.

• 2001, together with Prof. M. Wang of Northeastern University and Prof. A. Jarosevic of Comenius University, Dr. Sumitro developed a Real-Time True-stress Monitoring System for steel cables in Ashidagawa Cable Stayed Bridge. Actual-stresses of main-cables are monitored by pulsed Elasto-Magnetic (EM) sensory technology. Following the success of this existing stress evaluation in this bridge, this EM system has been used world-wide, such as Qian Jiang Bridge (2002) and Zhan Jiang Bridge (2003) in China, and Waldo-Hancock Bridge Project, Maine, USA (2006).

• 2002, Dr. Sumitro participated in the Research, led by Prof. Uomoto of the University of Tokyo, on Upgrading of Soundness Evaluation Method for Highway PC Bridge, this research project was funded by Ministry of Land, Infrastructure, Transport and Tourism, Japan through Japan Prestressed Concrete Contractors Association. This research is culminated in Technical Note of National Institute for Land and Infrastructure Management, No. 613, October 2010, ISSN 1346-7328.

• 2005, together with Prof. Y. Ito of Saga University and Prof. H. Matsuda of Nagasaki University, Japan, Dr. Sumitro developed a Smart Line Imaging Tracer (SLIT) System to evaluate actual-stresses distribution in existing post tensioned bridges. This NDE method has been applied at several bridge sites to estimate current stresses of existing PC tendons such as Okinawa Bridge, Osaka Bridge and Chiba Bridge.

• 2007, Dr. Sumitro involved in the corrosion monitoring of main cable for suspension bridges mock up test at Columbia University, NY, funded by FHWA. He estimated the actual stress of the main cable by using elasto-magnetic approach.

• 2009, together with Prof. Y. Ito of Saga University, Dr. Sumitro involved in the development of Bridge Cable Visual Inspection Robotic system for stayed and suspended cables. This NDE method can be controlled remotely with wireless communication and has been applied at several bridge sites to evaluate bridge cables’ condition such as Ashigara Bridge, Tokyo Nagoya Expressway.

• 2010, together with Prof. Matsuda of Nagasaki University, S. Nishimura of Keisoku Research Consultant, Dr. Sumitro involved in the development of NDE drone by integrating UAV technology, RTK-GPS and advanced camera technology. This NDE method has been applied at several infrastructures to evaluate structural integrity condition of bridges and historical buildings.

• 2011, together with Micron Optics, Dr. Sumitro developed detachable and reusable FBG long-gauge fiber optic displacement sensors. One of the applications is to test the functionality of damper lock-up system on highway bridges.

• 2012, together with Resensys, Dr. Sumitro developed Smart Wireless Sensor System for structural condition assessment of infrastructures such high rise buildings, seawall safety, tunnel safety and maximum, minimum and present (MMP) displacements of railway bridges of Shinkansen bullet train due to earthquake severe impact load.
