Welcome to our group’s website at Rice University. We welcome you to explore our website for current activities and news. Our group focuses on research in the broad area of structural dynamic systems, smart structures, system identification, structural health monitoring, sensing and monitoring of structures subjected to earthquake, wind and waves, seismic protection and applied nanotechnology related to sensing. Our goal is innovation and creative research. Our work includes theoretical, analytical and experimental studies. We focus mainly on mathematical modeling and development of advanced algorithms for system identification, monitoring and control for seismic and vibration protection. We believe in experimental verification of cutting edge ideas that we develop (although this is only small percentage of our overall effort). We collaborate with researchers within Rice and other universities worldwide. We welcome collaboration. Please do not hesitate to contact us if you have any questions.
I hold a joint appointment between the Civil and Environmental Engineering Department, and the Mechanical Engineering Department at Rice University. I am a tenured full professor since 2006. I obtained my Ph.D. (1987-1990) from State University of New York at Buffalo, where I was a post-doctoral researcher before I started my academic career in 1993. My teaching and research interests are in the areas of structural dynamic systems; seismic protection; earthquake engineering; smart structures; system identification; and structural health monitoring and applied Nanotechnology. My research is funded by the NSF, NASA, Department of Energy, Air Force Office of Scientific Research, Office of Naval Research, other State, Federal, Private Agencies and Industries. National Science Foundation has awarded me the prestigious faculty early CAREER award for innovative research in Adaptive Stiffness Structures.
Our group has developed advanced modeling and numerical techniques for nonlinear dynamic analysis of base isolated structures. Such development lead to the compute program 3D-BASIS has been used for analysis and design of numerous base isolated structures within the United States and in many countries around the world. Landmark structures where 3D-BASIS was used are the New San Francisco International Airport and the San Francisco General Services Building, both of which are supported on friction pendulum bearings.
Our group’s research thrust in earthquake protection, vibration isolation, and smart structures has focused on adaptive passive stiffness structures, variable stiffness and damping structural systems. Our group has performed widely cited research on adaptive stiffness structural systems and smart tuned mass dampers. Our group has developed widely cited benchmark problems on smart base isolated structures.
Our group’s research thrust in system identification and structural health monitoring has centered on the development of new low rank, sparse, compressive sensing, and time-frequency algorithms.
In an Institute/center funded by NASA (Texas Institute of Intelligent Bio-Nano Materials and Structures for Aerospace Vehicles—co-principal investigator) our group developed advanced real time fault detection and system identification algorithms for structural, actuator and sensor failure. Our team also conducted widely cited research on nanocomposite based strain sensing in the NASA funded study. We are currently performing research on laser based non-contact strain sensing with funding from Office of Naval Research.
My editorial activities include service as the managing editor of the journal of structural engineering [ASCE International journal], Editor of the structural control and health monitoring journal [Wiley International Journal] and Editor-in-chief [North America] of Structural Monitoring and Maintenance [Techno-press International Journal]. Structural Engineering Institute (SEI) of ASCE elected me as an inaugural fellow in 2012. I served as the chair/vice-chair/secretary/member (2006-to-2012) of ASCE, SEI, Technical Activities Division Executive Committee—the highest technical body in Structures Division. I served as a member of the board of directors of the international association of structural control and monitoring (2008-2012). I served as the President of the U.S. panel on structural control and monitoring (2006-2008). I was the founding chair of ASCE structural health monitoring committee (2004-2006), ASCE-Engineering Mechanics Institute, and chair of the structural control committee (1998-2002), ASCE Structural Engineering Institute.
