- Spring 2015: Math 2940
- Spring 2014: Math 2930 Differential Equations for Engineers
- Fall 2013: Math 2940 Linear Algebra for Engineers
- differential equations: notes , an ode applet, PDE applets heat equation in 2d , wave equation in 1d , wave equation in 2d , Laplace equation in disc .
- other applets: display vector fields , linear algebra , moving iterated function system , maps of the plane , a pendulum , and free source code.
- other notes: the Poincare Lemma , differential forms , det , classic guitar construction-say that's not Math.
- teaching toys: trig , spherical and cylindrical coords , surface area .

- a family of solutions to the Euler system and poster about them from a SIAM nonlinear wave meeting,
- a translation of Leray Sur le Mouvement d'un Liquide Visqueux Emplissant L'espace
- a translation of Nash Le Probleme de Cauchy pour les Equations Differentielles d'un Fluide General
- are these boundary conditions ever used?

- tensegrity catalogue,
- A cyclic flex of the Connelly-Steffen surface .
