Naiomi T. Cameron

Associate Professor of Mathematics and Associate Dean of the College of Arts and Sciences


My scholarship lies in the field of algebraic and enumerative combinatorics.  The objects of study in my research have included the Riordan group, Fibonacci tableaux, combinatorial determinants and dessins d’enfants.  The main recurring theme of my research is the pursuit of new combinatorial insights which uncover new or illuminate existing algebraic knowledge.


Courses I have taught include Introductory Statistics, Calculus, Discrete Mathematics, Linear Algebra, Differential Equations, Number Theory, Combinatorics, and Abstract Algebra.
