Research
My research interests lie at the intersection of analysis, geometry, partial differential equations, and their computational aspects. Lately, I have been looking at the finite element exterior calculus (FEEC), working with Hilbert complexes in general, and the general nature of boundary value problems. I successfully defended my PhD on 6/4/2015; the thesis is available here, with supplemental files here. An extended version of my PhD thesis with supplementary notes is available here. Or buy the bound version at Lulu.com.

Notes
Notes on Tensor Analysis
Notes attempting to demystify some of the vagaries of tensor analysis. Many issues raised in that document have since been resolved; updates forthcoming. In the meantime, a more concise version of this is included in Chapter 1 of the extended version of my thesis.

Why gradient vector fields have no curl
This phenomenon occurs in more general versions quite routinely in my research. Also, the proof that your parents lied to you when they said when they were your age, they had to walk to school uphill both ways.
