The Kirkman Medal recognizes outstanding work by ICA members in their early research careers; it is not an award for an excellent PhD thesis. At most 3 Kirkman medals per year may be given. Recipients must have received their doctorates during [the four years prior to the award]. Nominations should be made by two Fellows of the ICA, and should be accompanied by a curriculum vitae and a letter explaining the importance of the nominee's research.

My apologies for incomplete information about some recipients. I hope to complete this page with the full citation for each recipient and links to personal pages  alas, when there is time...For now the citations for Jonathan and me will have to suffice.
Robert Craigen has developed a very original method of composing matrices that he calls the "weaving method" and has used this method in the construction of Hadamard and weighing matrices. In the century since Hadamard's original conjecture concerning Hadamard matrices, there have been only two major advances in knowledge of the general existence of these matrices. The first was the Seberry theorem (1976); the second is a result of Craigen's that is even stronger than the Seberry result.
Craigen has also developed the theory of signed groups and has used it to give Hadamard matrices with cocyclic development; he has also used the representation theory of signed groups to find new nonexistence results for weighing matrices. His work on complex Golay sequences, as well as his work on multiplciation of an arbitrary number of sequences with zero autocorrelation, has led to the construction of new Hadamard matrices.
Robert Craigen is recognized as a leading expert in matrix
composition,
the theory of signed groups, and the study of
(0,1)determinants.
He has been invited to write three sections in the forthcoming
CRC Handbook
of Combinatorial Designs; this is a recognition of both his
research achievements
and his skill in lucid exposition.
Despite the fact that he is working outside academia, Jonathan has made fundamental contributions to the theory of difference sets and perfect binary arrays. He has made extraordinary progress in using diverse mathematical areas to contribute to the theory of difference sets. One expert labelled his construction that showed that every abelian 2group of order 2^{2a+2} and exponent less than 2^{a+3} has a difference set as "the only completely satisfactory result in the theory of difference sets." Among other important results which he discovered, or in which he played a major role are: the nonexistence result establishing that the exponent of the group is not a necessary and sufficient condition for the existence of a difference set; characterization of groups that can contain a McFarland difference set; a structure theorem that determines precisely what Hadamard difference sets must look like for primes other than 2 or 3. Recently he has discovered a new family of parameters that have difference sets; this is the first new parameter family containing difference sets that has been found in 20 years; it includes as subfamilies almost all known families of difference sets, and it yields an infinite family of new groups that contain a McFarland difference set. This major breakthrough will have an important unifying effect in the study of difference sets.
Jonathan Jedwab has made substantial contributions in both
practical
research and theoretical combinatorics; he is already recognized
as a leading
expert in the theory of difference sets.
