 Educational Background/Employment:
  • S.B. (2005) Mathematics (Applied Option), Massachusetts Institute of Technology
  • M.S. (2007) Mathematics, Texas A&M University
  • Ph.D. (2011) Applied Mathematics, Northwestern University
  • Professional Training:
    • 2011-2013 NSF Mathematical Sciences Postdoctoral Research Fellow, Complex Fluids Group, Department of Mechanical & Aerospace Engineering, Princeton University

Research Interests:

  • Complex and Nonlinear Systems: the study of the mechanics of natural phenomena using advanced mathematical techniques and state-of-the-art computational simulations; in particular: diffusion, mixing and self-organization of granular matter, flow in heterogeneous porous media, multiphase interfacial instabilities, fluid-structure interaction, shock-formation in compressible flows, viscoelastic flows and non-Newtonian rheology, dynamics of coherent structures in nonlinear wave equations, nonlinear Fourier analysis of physical data.
