## About Me:

I am a Ph.D. candidate in the Department of Mathematics and Statistics at Washington State University working with Dr. Michael J. Tsatsomeros. Prior to my studies at WSU, I obtained my bachelor's degree in mathematics (2007) and my master's degree in applied mathematics (2009), both at the University of Washington in Seattle. I spent three years, thereafter, as an instructor of mathematics at South Seattle College and Green River College.

My research interests lie in matrix theory, partial differential equations, complex analysis, numerical analysis, and dynamical systems. My current research focus is on the theory and applications of P-matrices, stability theory, and spectral analysis of interval matrices. Recent interests include complementarity problems, matrix mobius transformations, and the interval eigenvalue problem.
