Thomas R. Cameron is an assistant professor of Mathematics at Penn State Behrend. He is a passionate mathematics teacher and scholar whose interests lie at the intersection of algebraic graph theory, data science, and numerical analysis. In particular, his work has made notable contributions to the area of matrix polynomials, the numerical solution of polynomial equations, the characterization of digraphs, and the rankability of data.

Research Interests

Numerical linear algebra: study of matrix polynomials, the non-linear eigenvalue problem, and the numerical solution of polynomial roots; Algebraic graph theory: study of graphs using the algebraic properties of their associated matrices; Rankability of data: study of data and its inherent characteristics that make it more or less suitable for ranking
