Early intervention systems for adverse police interactions.

  • Working in a team of four graduate students/post-docs to expand a machine-learning based model to predict adverse police-citizen incidents.
  • Part of the Eric and Wendy Schmidt Data Science for Social Good Summer Fellowship in Chicago, IL.

SMPM: Incompressible Navier-Stokes Solver

  • Modeling of shoaling nonlinear internal waves over a shallow, sloping bathymetry.
  • A fortran90/Matlab suite of tools to solve the incompressible Navier-Stokes equations with a high-order element-based discretization and a Schur-complement based domain decomposition. Under development with Greg Thomsen and Peter Diamessis.

Deflation of Schur complements of elliptic problems

  • Use of deflation alongside block-diagonal preconditioning for designing a parallel sparse matrix solver for elliptic FEM problems.
  • Acheives convergence rate of GMRES independent of grid deformations and grid size.

High-order FEM acoustic propagation through incompressible flows

  • High-frequency rough-surface scattering using COMSOL FEM and Matlab-based boundary element methods.
  • High-order continuous spectral element collocation method for sound propagation through moving incompressible flows.
