I am an evolutionary ecologist with a strong interest in behaviour. I am most interested in the patterns of sexual and social selection that lead to differences among individuals in both behaviour and fitness, and how these differences knit together through social interactions to produce the complex phenomena we see around us. I favour observational studies of animals in the wild combined with statistical methods such as mixed linear models and social network analysis to explain the observed behaviour and social interactions.
I am currently working on the Kluane Red Squirrel Project (KRSP) with Andrew McAdam. My interest focuses on how individual phenotypes are shaped by their competitive environment, made up for the genotypes of other individuals. This involves analysis of the long-term KRSP data set, going back to 1987, but also field work in the Yukon. We identify individual red squirrels, genotype them and track them throughout their lifetimes, locating their territories and who they interact with. This will allow us to determine genetic components to competition, the effect this has on phenotypes, and then to predict the subsequent evolutionary trajectories.
