My research program focuses on understanding the genetic basis of evolutionary change. In particular I am concentrating on two major components of the evolutionary process. Firstly, I study how genetic differences among individuals lead to variation in the numbers and survival of their offspring (fitness). Secondly, I determine how those genetic differences can become partitioned between populations when they begin to diverge genetically into different species. Salmonid fishes (Atlantic salmon, Arctic charr, rainbow trout, brook charr) continue to be the models for most of this work because their biology makes them interesting candidates for genetic analysis.

We address how biodiversity arises especially in single populations of fishes composed of alternate ecotypes that live in different lake habitats. We study the factors that regulate the formation of these specialized ecotypes and have expanded theory by evaluating the role of phenotypic plasticity in adaptive biodiversity formation. Experience working with fish resource polymorphism since 1993 uniquely positions us to investigate how novel ecotypes evolve and may be converted into new species in the future countering biodiversity loss. We also study how commercial fishing affects fish traits in natural populations. Our focus on the diverse kinds of fish in natural populations is important because this is rarely considered in the contexts of ecological function, management and conservation.
