I have been teaching mathematics courses at the university level for over 15 years, including service courses, graduate courses, computer sessions, and large freshman classes, as well as mentoring Research Experience for Undergraduates (REU) students. Each group and each student is a challenge, and I always try to find ways of teaching that work best for them and for the subject. Most of this time I have taught in the US, first as a GTA at Kansas State University, then as a Boas assistant professor at Northwestern University and currently as an assistant professor at UHD.
After coming to Houston I developed several new research collaborations, some with the CMS faculty. Collaborations in analytical mechanics, applied statistics and mathematical biology resulted in published and submitted papers to peer-reviewed journals in 2010-2012. These cover such topics as applications of positive evolution equations to mathematical biology, and synchronization of nonlinear oscillators applicable to various areas where collective behavior is observed.
I also published a paper that applied geometry to physics and submitted one on stability of operator equations that occur in optimal control problems. Currently, I am working on developing new approximation techniques for non-traditional problems in mathematical physics and continue my work on operator equations. Some of my newest work is in mathematical biology, I am currently working with Mike Tobin from the Natural Sciences department on developing a model of water transport in trees. Aside from purely scientific interest we plan to use this model as a basis for senior and REU projects for students. Another new project is in the spectral graph theory, it is a study of asymptotic spectral invariants of band, block-circulant and block-Toeplitz graphs. These graphs appear in organic chemistry and require a mix of linear algebra and probability theory for their study aside from the graph theory itself. Awards
