Welcome

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. I am gradually moving my academic homepage to a new site. The older material will remain available 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 my newer publications page.

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

In Fall 2026 I am teaching Math 271 (Linear algebra and PDE). In Winter 2027 I am scheduled to teach Math 263 (ODE for engineers) and Math 595 (Rigorous and computational aspects of lattice QFT).
