ABOUT ME

I’m a Research Associate of Applied Mathematics at the University of Washington. My areas of interest are numerical analysis and computation.

My curriculum vitae can be found here.

RESEARCH

Software

Some of my scientific software is freely available on GitHub:

  • optdmd — a MATLAB software package for computing the optimized dynamic mode decomposition (DMD).

Preprints

My preprints can be found on the arXiv e-print server:

Publications

My work which has appeared in scientific journals:

  • Travis Askham and Antoine Cerfon. An adaptive fast multipole accelerated Poisson solver for complex geometries. J. of Comp. Phys. In press. DOI
  • Travis Askham and Leslie Greengard. Norm-Preserving Discretization of Integral Equations for PDEs with Internal Layers I: The One-Dimensional Case. SIAM Rev., 56(4):625–641, 2014. DOI

Thesis

My Ph.D. thesis focused on integral-equation methods for the solution of inhomogeneous elliptic partial differential equations in complex geometry. It can be downloaded here. The “heuristic” discussion of error found in section 1.4.7 has been superseded by the discussion in this paper.
