Kathy Horadam is a mathematician recognized for her contributions to combinatorial design theory, particularly in the study of Hadamard matrices and recursive integer sequences such as generalized Fibonacci numbers. She is the author of the monograph Hadamard Matrices and Their Applications (Springer, 2007), which surveys the construction, classification, and applications of Hadamard matrices in areas including coding theory, signal processing, and experimental design. Horadam has also published research articles on the properties of linear recurrences, extending classical results on Fibonacci and Lucas sequences to broader families now often referred to as “Horadam sequences.”
Academic affiliations reported in scholarly publications include the University of Queensland in Australia, where she has held a research position in the School of Mathematics and Physics. Her work is frequently cited in the literature on combinatorial designs, orthogonal arrays, and number theory.
