Sumeet is a PhD student working with Professor Katerina Ziotopoulou at University of California, Davis. He is currently working on a project funded by Caltrans on ‘evaluating and estimating the liquefaction induced downdrag on axially-loaded piles’. The project aims at performing two large centrifuge model tests with different soil straitography in order to investigate the different mechanisms that affect the performance of piles in liquefiable deposits. It also aims at contributing in the revision of existing design procedures to better and cost-effectively design piles in liquefiable soils. Ultimately, findings are expected to be used to further understand the re-consolidation phase of liquefaction as well as validate and advance the existing numerical models.
Sumeet earned his Bachelor of Technology (B.Tech) in Civil and Environmental Engineering with minor in Computer Science from Indian Institute of Technology (IIT) Delhi in 2014. After graduation, he spent 10 months as a research assistant in 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, he joined Computational Mechanics Group at University of California, Davis. His research focused on the study of non-linear effects in soil-structure interaction systems. He developed new non-linear normal contact and shear interface elements to accurately model the soil-structure interface for dry as well as fully/partially-saturated soil conditions (Sinha,S.K. 2018). He also developed pre-processor gmESSI , post-processor pvESSI and integrated with Real ESSI (now called MS-ESSI) Simulator (http://ms-essi.info/) to make it a complete Finite Element Simulation system along with optimizing it’s output and parallel implementation for running large simulations. With these developed contact models and nonlinear materials , studies are now being performed to evaluate the nonlinear effects of Soil-Structure Interaction on Nuclear Power Plants (link_1, link_2) and Submerged Modular Reactors (link_1, link_2). He completed his master’s degree in December 2017 and continued his Ph.D. at UC Davis but now on a more experimental side to get a holistic understanding, and experience of geotechnical engineering and practice.
Currently, he is serving as the webmaster of the Geotechnical Graduate Student Society (GGSS) and Vice President (Finance and Operations) at the Indian Graduate Student Association (IGSA) at UC Davis. At times, he engages himself in carrying out outreach activities for undergrad and K-12 school students.
