Currently working as Junior Professor at the University of Stuttgart, sponsored by fischerwerke GmbH & Co. KG (links to article 2 and article 3), and leading the department on Innovative strengthening methods using fastenings. Received Ph.D. in 2013 from the University of Stuttgart for the thesis titled “Seismic Behavior and Retrofitting of RC Frame Structures with Emphasis on Beam-Column Joints – Experiments and Numerical Modeling”. Previously worked as Scientific Officer at Bhabha Atomic Research Centre, Mumbai from 2004 to 2013. From 2013 to 2016, worked as the group leader and senior research engineer at the Institute of Construction Materials, University of Stuttgart. Authored more than 180 research papers including more than 60 papers in peer-reviewed international journals. Also serving as the technical secretary for the fib TG 2.9 (Fastenings) committee and as a member of the fib TG 2.5 (Bond), ACI 355 (Anchorage) and ACI 408 (Bond) committees. Peer reviewer and guest editor for several international journals. Research interests: Seismic assessment and strengthening of RC frame structures; Fire performance of RC structures; Anchorage in concrete construction; Impact behavior of RC structures; Behavior and strengthening of RC structures subjected to corrosion; Development of new construction materials; Computational modeling of concrete structures; Development of spring models for structures and structural components.

My Research Focus
Reinforced concrete structures are subjected to different types of natural and man-made hazards during their lifetime. These hazards might be in the form of extreme loadings e.g. earthquakes, fire, impact, explosions or in terms of chronic deteriorating loadings due to environments such as corrosion or fatigue. Traditionally the design of structures is done following the linear analysis and force-based design principles. Such designs work well provided (i) a good estimate of the load can be done and (ii)the structure remains within the linear range. This is applicable only in case of normal gravity loads that can be estimated well on the higher side and the structure is designed to withstand these loads within the linear range. However, for any kind of hazardous load as listed above, this is no longer valid. On one side, it is very difficult or even impossible to predict the extent of load that the structure might be subjected to. On the other side, since these loads are relatively infrequent, it is highly uneconomical to design them to resist such loads by remaining within linear range. As soon as the structure goes into the nonlinear (inelastic) range, the linear force based design principles become invalid and the structures designed with such rules might behave in an unprecedented and unacceptable manner. It is the responsibility of the structural engineer that the structure designed by him/her performs in a way as is desired from it. This can only be done if the design of the structure is carried out not on the basis of linear force based analysis but on the basis of nonlinear (inelastic) performance-based analysis. This has been the primary focus of my research work. Since 2004, the major fields of my research are:
- – Performance assessment of concrete structures under earthquakes
- – Performance assessment of concrete structures subjected to fire
- – Behavior of concrete under impact
- – Developing innovative retrofitting solutions for concrete structures
- – Anchorages in concrete construction
- – Development of advanced materials
