Constructions using Number Theory and Linear Algebra

Emeritus Professor Mieko Yamada of Kanazawa University graduated from Tokyo Woman’s Christian University and received her Ph D from Kyusyu University in 1987. She has taught at Tokyo Woman’s Christian University, Konan University, Kyushu University, and Kanazawa University. Her areas of research are combinatorics, especially Hadamard matrices, difference sets and codes. Her research approach for combinatorics is based on number theory and algebra. She is a foundation fellow of Institute of Combinatorics and its Applications (ICA). She is an author of 51 papers in combinatorics and number theory.
Emeritus Professor Jennifer Seberry graduated from University of New South Wales and received her Ph D in Computation Mathematics from La Trobe University in 1971. She has held positions at the Australian National University, The University of Sydney, University College, The Australian Defence Force Academy (ADFA), The University of New South Wales, and University of Wollongong. She served as a head of Department of Computer Science of ADFA and a director of Centre for Computer Security Research of ADFA at University of Wollongong. She has published over 450 papers and eight books in Hadamard matrices, orthogonal designs, statistical designs, cryptology, and computer security.
