## Teaching & Office Hours

In SP15, I am teaching two sections of Math 232: Calculus with Functions II. My office hours are:and reflect the results of a Doodle poll. I'm often in my office in ROOP 106, so feel free to stop in whenever my door is open. My current schedule is available online: here.

## Research Interests

I am interested in applying mathematics to physical problems. I have worked on problems from atmospheric science, coupled multi-physics, porous media, and nonlinear waves. I'm currently thinking about analytic continuation and ODE. I use both analytic and numeric techniques, while drawing on aspects of dynamical systems, PDE theory, functional analysis and numerical analysis. More specific information can be found here. Links to papers are found here.I'm also involved in the M-cubed program, a six-week summer National Research Experience for Undergraduates Program (NREUP) funded by the MAA. Read more about the NREUP, and about the JMU M-cubed program.
