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. My most recent work has been in support of an efficient power-series based algorithms in missile trajectory simulation. With my collaborators in the JMU PSM group, we've developed a family of high fidelity and efficient trajectory models for the 3 degree-of-freedom (3 DOF), 3+3 DOF, and full 6-DOF models, under a 1976 atmosphere and J6 gravity. We are always looking for JMU students as collaborators in this work, and have been fortunate to attract grant funding that allows us to support some of these students in summer positions. I use both analytic and numeric techniques, while drawing on aspects of dynamical systems, theory of differential equations, 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. While the bad news is that we are currently unable to apply for the external funding that supports this program, the good news is that we are ineligible because JMU is national REU site!
