GENERAL BACKGROUND

Dr. Krauthammer is currently Goldsby Professor of Civil Engineering at the University of Florida, and Director of its Center for Infrastructure Protection and Physical Security (CIPPS). Until the end of 2006 he was Professor of Civil Engineering at the Pennsylvania State University and Director of the Protective Technology Center (PTC). He obtained his Ph.D. in Civil Engineering from the University of Illinois at Urbana-Champaign. His main research and technical activities are directed at structural behavior under severe dynamic loads, including considerations of both survivability and fragility aspects of facilities subjected to blast, shock impact, and vibrations. He has specialized in the nonlinear behavior of structures (including medium-structure interaction) under seismic or impulsive loads, and the development of numerical simulations and testing techniques for structural assessment. His work has included the development of design recommendations for enhancing structural performance, physical security and safety of buildings, facilities and systems. Additionally, he has been involved in the response, safety, and physical security assessment of buildings and facilities before and after abnormal loading events. He conducted both numerical simulation, and experimental studies of structures subjected to a broad range of loading conditions. His research has been supported by the Department of Defense Explosive Safety Board, Defense Threat Reduction Agency, Federal Highway Administration, Minnesota Department of Transportation, National Science Foundation, NATO, Norwegian Defence Construction Service, US Air Force, US Army, US Marine Corps, US Navy, and the Pennsylvania Department of Transportation.

Dr. Krauthammer is a Fellow of the American Concrete Institute (ACI), a member of the American Society of Civil Engineers (ASCE), and a member of the American Institute of Steel Construction (AISC). He is involved with other national and international professional organizations. He serves on ten technical committees of ASCE, ACI, and AISC. Dr. Krauthammer is chair of the ASCE Task Committee on Structural Design for Physical Security, and Chair of the Joint ACI-ASCE Committee 421 on Design of Reinforced Concrete Slabs. He was the founding Chair of ACI Committee 370 on Short Duration Dynamics and Vibratory Load Effects. Also, he was Chair of the ASCE Engineering Mechanics Committee on Experimental Analysis and Instrumentation and of the ACI Committee 444 Experimental Analysis of Concrete Structures. He was a member of the National Research Council Defensive Architecture Committee. Dr. Krauthammer has written more than 380 research publications, and has been invited to lecture in the USA and abroad. He has been a consultant to industry and governments in the USA and abroad.
