I am a Ph.D. student in the Ziotopoulou Research Group at the University of California Davis. My current research work is on “Validation of Design for Liquefaction-Induced Downdrag on Piles“. I performed two large (9 m radius) centrifuge tests to study the mechanism of liquefaction-induced downdrag on piles. A numerical method using TZLiq and newly developed QZLiq spring was developed and implemented in OpenSees and validated against centrifuge test results to model liquefaction-induced downdrag on piles. Currently, I am working on finalizing a simplified procedure for design of piles in liquefiable soils for extreme loading conditions (during shaking and from liquefaction induced downdrag). Parallelly, I am also developing a  web app for generating  input ground motions for nonlinear deformation analyses following the double convolution approach, which is expected to ultimately facilitate and increase the use of ground motion seismic recordings by practitioners.

I earned my bachelors from in Civil and Environmental Engineering with minor in Computer Science from Indian Institute of Technology (IIT) Delhi in 2014. After graduation, I spent about 10 months as a research assistant at IIT Delhi studying stochastic 1-D equivalent linear seismic ground response analysis of Delhi to verify the existing Indian Standard (IS) codal provisions and provide recommendations. In April 2015, I joined the Computational Mechanics Group at UC Davis where I worked on the development of Real ESSI. I developed the pre-processor gmESSI, the post-processor pvESSI and integrated them to Real ESSI to make it a complete Finite Element Simulation system along with optimizing it’s output and parallel implementation for running large simulations. I also developed non-linear normal contact and shear interface elements to model the soil-structure interface for dry as well as fully/partially-saturated soil conditions. With these developed models, studies were performed to evaluate the nonlinear effects of soil-structure interaction on nuclear power plants (link1, link2)and submerged modular reactors (link1, link2).
