1. Graduate Research Assistant at Vanderbilt University, Nashville, TN (05/2013-05/2017)

• Multiscale-multiphysics modeling of structures subjected to extreme environments:
  
  1. Formulated and implemented the variational multiscale enrichment (VME) method (in C++) to model the elasto-viscoplastic behavior of structures with heterogeneous materials
  2. Incorporated heat transfer and corrosion problems into the VME framework to model damage evolution due to environmental degradation
  3. Developed the reduced order variational multiscale enrichment (ROVME) method to improve the computational efficiency of the VME method
  4. Enhanced the ROVME computational framework to account for coupled thermo-mechanical effects
  5. Developed the hybrid multiscale integration method to model damage and fracture in structures subjected to surface degradation

2. Intern at ExxonMobil, Upstream Research Company, TX  (05/2016−08/2016)

• Automated geomechanical analysis of faulted reservoirs:
  
  1. Developed and implemented an advanced numerical algorithm (in C++) to automate geomechanical analysis of reservoirs with complex fault networks
  2. Contributed in automated mesh generation for reservoir models with explicitly represented faults
  3. Improved the Discontinuous Galerkin (DG) treatment of non-conforming meshes and faulted surfaces
  4. Modeled slippages of faults due to pore pressure change which are verified by extended finite element method (XFEM)
     
  5. Designed a post-processing algorithm to visualize slippages along the faults
