It is with great pleasure that the Canadian Applied and Industrial Mathematics Society presents the 2018 Cecil Graham Doctoral Dissertation Award to David McLeod.

Dr. McLeod’s thesis is a beautiful example of applied mathematics, applying sophisticated mathematical ideas to questions of fundamental interest to evolutionary biologists, relating to infectious diseases and mating systems, including sexual selection and conflict, and also addressing social interactions such as cooperation, altruism and spite, for example showing how small population size can drive the emergence of such behaviour.
