Biography
I received my doctoral degree from the University of Toronto in 2015, working with Dr. Hernan Lopez-Fernandez on the evolution and functional morphology of Neotropical cichlids. I was an NSERC postdoctoral fellow in Dr. Sharlene Santana's lab at the University of Washington from 2016 to 2019, studying skull shape and feeding biomechanics in bats. In my research I am interested in better understanding the uneven distribution of diversity across the tree of life, especially the diversity of for...

I was an NSERC postdoctoral fellow in Dr. Sharlene Santana's lab at the University of Washington from 2016 to 2019, studying skull shape and feeding biomechanics in bats. In my research I am interested in better understanding the uneven distribution of diversity across the tree of life, especially the diversity of form and function. My work takes an integrative approach, applying comparative methods to data on biological shape, biomechanics, feeding ecology and behaviour to understand the relationship between adaptive divergence and the diversity of vertebrate radiations.
