I am an associate professor of mathematics at McGill University. I am from Mongolia, and did my PhD at Utrecht University with Rob Stevenson and Hans Duistermaat. Before coming to McGill, I was a postdoc at UCSD with Mike Holst. My mathematical genealogy page is here.

My research generally concerns analysis of partial differential equations and of numerical algorithms for solving them. I have worked on existence theory of a semilinear elliptic system arising in general relativity, detailed analysis of equations similar to the Navier-Stokes system, optimal complexity bounds on some adaptive numerical methods for solving elliptic boundary value problems, a nonlocal generalization of the isoperimetric problem, and certain combinatorial approximations of the exterior calculus. Currently I am working on projects related to elliptic regularity theory, the Navier-Stokes equations, conformal geometry, and adaptive numerical methods. My publications can be found at Google Scholar, at arXiv or on this page.

I enjoy making simple illustrative simulations. Have a look at animations of ancient planetary models.

This fall I am teaching a introductory graduate course on functional analysis. Then in the coming winter, I will teach a second graduate course on partial differential equations, and an honours course on ordinary differential equations.
