My research focuses on finding families of periodic multidimensional continued fractions by expanding on the work of Dasaratha et al. in higher dimensions. I also have found connections between the matrix analog of the Jacobi-Perron algorithm for multidimensional continued fractions and the combinatorial construction of Riordan arrays. I am working with Dr. Matt Hudelson.

I have also worked with a research group to explore new operations on Riordan arrays.
