My research interests center around the interactions of drift, selection, mutation, and demography. As a population geneticist, I study how complex demographic histories impact the evolutionary process through time and space. These complex histories, such as range expansions and population bottlenecks, can lead to non-equilibrium scenarios where the fate of both beneficial and deleterious mutations can be influenced more by drift than selection. I aim to understand whether and how this impacts genetic diversity of populations as they adapt to new environments, and if this can lead to false inferences of loci under selection.
I address these questions through both simulation and comparison to genomic data, to uncover the disparities that arise between ideal controlled situations and complicated, real-world biological scenarios. I also have previous and ongoing work on the topics of Qst-Fst analyses, estimation of effective population size, local adaptation in lodgepole pine, and the impact of mating systems on the estimation of the distribution of fitness effects for new mutations (DFE).
