Capsella introgression

I am wrapping up a collaboration with Martin Lascoux’s group looking at signals of subgenome specific introgression in the tetraploid, Capsella bursa-pastoris, from the congeners C. orientalis, C. grandiflora, & C. rubella.

Dynamics of evolution in Daucus carota 

I am starting a new project in collaboration with Tyler Kent, investigating the temporal change in allele frequency in populations of Daucus carota (Wild Carrot, Queen Anne’s Lace). We have 6 years of data (seed) collected by Aneil Agrawal, Stephen Wright, and John Stinchcombe, that is scheduled to be grown up this year. I’m really excited for what this project has in store. This biennial plant could provide some really interesting genetic structure over the years, we also hope to relate changes in allele frequency to fitness through the use of a common garden experiment. Here are some pics from when we all went up to KSR to do some seed collections:

 

Rapid adaptation to pollutants in Duckweed, Lemna minor

In collaboration with Jason Laurich, a PhD student here at EEB UofT, I will be investigating the genetic basis of adaptation to pollutants of the predominantly asexual plant, duckweed. Jason has been collecting populations of duckweed across a gradient of pollutant concentrations and types in wastewaters, and I will be examining whether well-adaptated populations vary in their rates of sexual reproduction.
